3. Heard the learned counsels appearing for the petitioners and learned Special Government Pleader appearing for the respondents.
4. By consent of both parties, the writ petitions are disposed of finally.
5.Dr.A.Gubendran, Associate Professor, Saraswathi Narayanan College of Arts and Science, Perunkudi, Madurai, who appeared on behalf of the petitioners and Dr.S.Arul Antony and Dr. S.Chidambara Vinayagam, Associate Professors, Presidency College, Chennai, who appeared on behalf of the respondents rendered assistance to their respective learned counsels in resolving the issue raised in these writ petitions.
6.Upon discussion with the experts appeared on either side and considering the arguments of the learned counsels for both parties, the answers for the questions challenged in the respective Writ Petitions are given as below:-
Booklet Series 'A' - Question No.3:
The vibrational modes of representation for C2V point group is: C2V Gs;spj; njhFjp mjph;T tiffspd; FwpaPL:
7. Dr.A.Gubendran, Associate Professor, Saraswathi Narayanan College of Arts and Science, Perunkudi, Madurai in order to assist this Court, has argued on behalf of the petitioners that the Question No.3 in Booklet Series 'A' has no meaning without having a word 'Molecule'. At least the experts who have framed the question should have given the character table for C2V.
Without either of these two, it will be highly impossible for the candidates to opt any one of the options in the answers. However, this has been controverted by Dr.S.Arul Antony and Dr. S.Chidambara Vinayagam, Associate Professors, Presidency College, Chennai, who argued on behalf of the respondents, submitted that Dr.A.Gubendran is insisting upon the basic things by way of including the word 'Molecule' or the 'character table' which no doubt will give some basis or clue to the students to answer the question, but for the Post Graduate level, it is not necessary. Any student at the Post Graduate level, even without the assistance of the word 'Molecule' or 'character table', can simply answer this question.
7.1. I agree with the explanation offered by the experts namely, Dr.S.Arul Antony and Dr. S.Chidambara Vinayagam, Associate Professors and as such find that the TRB has rightly framed Question No.3 in Booklet Series 'A' and the key answer (A) given by the TRB cannot be found fault with.
Book Series 'A'- Question No.10.
Match the following:
Colour Sensitivity of air
(a) VCp2 - (i) pink - (I) inert
(b) CrCp2 - (ii) purple - (II) very high
(c) MnCp2 - (iii) Scarlet - (III) medium
(d) FeCp2 - (iv) orange - (IV) high bghUj;Jf:

8. Dr.Gubendran, Associate Professor, Saraswathi Narayanan College of Arts and Science, Perunkudi, Madurai, in order to assist this Court, stated that the answer given by the respondents, namely, word 'medium' cannot be correct and suitable, instead, it should be 'extremely air sensitive, which is not even given in one of the answers. He has also placed before me two text books, (i) Advanced Inorganic Chemistry, Vth Edition, (ii) Concise Inorganic Chemistry IVth Edition by J.D.Lee.
8.1. Referring to Page 689 of the book namely, Advanced Inorganic Chemistry, Dr.Gubendran submitted that 'very air sensitive' is also given as correct answer.
8.2. Again referring to another book, namely, Concise Inorganic Chemistry IVth Edition by J.D.Lee in Page 711, he submitted that the said book also supports his recommendation namely, 'extremely air sensitive' is the correct answer.
8.3. Per contra, Dr.S.Arul Antony and Dr. S.Chidambara Vinayagam disputing the arguments of Dr.Gubendran submitted that the only authoritative book is Principles of Organometallic Chemistry 2nd Edition, wherein, correct answer mentioned at page 280 is, 'sensitive air medium' and this book is recommended and universally followed by all the P.G. Students. But it is not known why students neglected to follow the said book and on the other hand referred to the other books.
8.4. The learned Special Government Pleader also submitted that when all other students attended the correct answer 'A' to question No.10, following the book namely, 'Principles of Organometallics Chemistry', only the petitioners have come to this Court challenging the correctness of the question No.10.
8.5. Since the learned counsels for the petitioners submitted that none of the answers given is matching and in view of the serious dispute with regard to the correct answer and two books referred by Dr.Gubendran also indicate that 'extremely air sensitive' is also the correct answer, it is proper to award one mark to the petitioners. Agreeing with the same, I hereby award one mark to this question.
Booklet Series 'A' - Question No.14:
Find out the value of electronegativity of an element whose ionisation energy and electron affinity are 17.41 eV and 3.45 eV.
madpahf;Fk; Mw;wy; kw;Wk; vyf;l;uhd; ehl;lk; kjpg;Gfs; KiwNa 17.41 eV kw;Wk; 3.45 eV nfhz;Ls;s xU jdpkj;jpd; vyf;l;uhd; fth;jd;ikiaf; fhz;f.
(A) 3.98 (B) 4.07 (C)3.24 (D)3.74
9.In respect of question No.14, Dr.A.Gubendran, referred the book namely, ''Selected Topics in Inorganic Chemistry'' by Wahind U.Malik, G.D.Tuli and R.D.Madan, reprinted in the year 2001. He argued that Question No.14 in Booklet Series 'A' has not been framed properly. Further, it is stated that although (B) is the answer given by the respondents, 'C' and 'D' are also correct answers which show that the respondents have misled the candidates. Hence, mark should be given to all the candidates who have chosen the answers 'A', 'C', and 'D', he pleaded.
9.1.However, Mr.VR.Shanmuganathan, learned Special Government Pleader with the assistance of two experts namely, Dr.S.Arul Antony and Dr. S.Chidambara Vinayagam, Associate Professors, Presidency College, Chennai, submitted that as per the book namely, ''Advanced Inorganic Chemistry, Volume 1'', Edition in the year 2015, by Sathaya Prakash, G.D.Tuli, S.K.Basu and R.D.Madan, which is the authorised book, Question No.14 has been properly framed and hence, option (B) is the correct answer.
9.2.Finally, it is argued on behalf of the petitioner that since there are misleading answers given in the above said two different books, one mark should be given to the petitioner. I agree with the said submission and I hereby award one mark to this question.
Booklet Series 'A' - Question No.15 Match the following:
Species Outer electron Shape bond-order (a) N (i) 18 (I) Planar triangle (x) 1.5 (b) O3 (ii) 24 (II) Linear (y) 1.33 (c) NO3- (iii)16 (III) V-shaped (z) 2.0 nghUj;Jf: mikg;G ntsp tbtikg;G gpiz tif vyf;l;uhd;fs; (a) N3 (i) 18 (I) Kf;Nfhz jsk; (x) 1.5 (b) O3 (ii) 24 (II) ePz;l tbtk; (y) 1.33 (c) NO3- (iii)16 (III) V-tbtk; (z) 2.0
10. Dr.A.Gubendran submitted that in Question No.15 of the Booklet 'A' series, N3 should have not been properly shown as N3- and without adding (-) with N3, the question has been wrongly framed. N3- should be mentioned specifically, to avoid confusion in the minds of the students and therefore, mark should be given to the students who answered this question.
10.1. However, this has been heavily disputed by the experts namely, Dr.S.Arul Antony and Dr. S.Chidambara Vinayagam, Associate Professors, saying that there is no N3 molecule at all. Since N3 was specifically mentioned in the species column in the question, the students are able to know that N3 species will convey only N3-. He also pressed into service a book namely, 'Concise Inorganic Chemistry' by J.D.Lee. Page 118 of the said book show that the species N3, O3, NO3-, in which N3 species need not carry minus (-) symbol.
10.2. Therefore, I agree with the submission made by the experts namely, Dr.S.Arul Antony and Dr. S.Chidambara Vinayagam, Associate Professors and the TRB has rightly framed this question. Hence, the answer for the Question No.15 is option 'A' which is correct.
Booklet Series 'A' - Question No.22 The mean life time of H-atom on the surface of a solid adsorbent at 298 K, if its desorption activation energy is 15 kJ Mol-1: [A0=10-13 seconds] xU jpl gug;Gfth; nghUspd; Gwg;gug;gpd; Nky;, 298 K -y; H-mZ gbAk; NghJ ruhrhp MAs;fhyk; kjpg;G vd;d? mjd; gug;G ePq;Fjy; fpsh;T nfhs; Mw;wypd; kjpg;G 15 kJ mol-1 MFk;: [A0=10-13 tpdhbfs;] (A) T=(10-13 s) e-5.37 (B) T=(10-13 s) e-6.05 (C) T=(10-13 s) e6.05 (D) T=(10-13 s) e5.37
11. Dr.A.Gubendran submitted that in the Question No.22, A0 should be mentioned as T 0. But the two experts namely, Dr.S.Arul Antony and Dr. S.Chidambara Vinayagam, Associate Professors, are not agreeing with the explanation given by Dr.A.Gubendran. Going by the majority view of experts, I am of the view that the respondents have rightly framed this question. Hence, option 'C' for the Question No.22, is correct.
Booklet Series 'A' - Question No.25:
12. Dr.A.Gubendran referring two books namely, Physical Chemistry Fourth Edition by Robert J.Silbey, Robert A.Alberty and Moungi G.Bawendi and Fundamentals of Molecular Spectroscopy by P.S.Sindhu, submitted that while mentioning linear Molecule, the respondents ought to have necessarily mentioned J 0,+2. While referring the book, Fundamentals Molecular Spectroscopy, he specifically mentioned that the question has been framed only from this book. He further submitted that a careful reading of page 121 of the said book clearly shows that Selection Rule for different Molecular symmetry indicates that a word 'pure' has to be mentioned. Without mentioning the word 'pure', the question would not be proper.
12.1. Replying to the above contention, the two experts namely, Dr.S.Arul Antony and Dr. S.Chidambara Vinayagam, Associate Professors, taking support from Atkins' Physical Chemistry by Peter Atkins, Julio De Paula at Page No.459, submitted that the word 'pure' is unnecessary. The specific selection rule be J=+2. The contention of the experts and the reference made by them at page 459 of the revised book shows that the question is correctly framed by the TRB, hence, I hold that the option 'C' for Question No.25 given by the TRB cannot be found fault with.
Booklet Series : Question No.43:-
Number of signals and their relative intensities for the NMR spectrum of ethyl benzoate respectively are:
vj;jpy; mrpl;nll;od; NMR epuypy; cz;lhFk; iriffspd; vz;zpf;if kw;Wk; mjd; bjhlh;g[ brwptpd; tpfpjq;fs; Kiwna (A)2, 1:2 (B)3, 3:2:5 (C)3,1:2:3 (D)4, 1:2:3:4
13. Dr.A.Gubendran, submitted that Question No.43 has been wrongly translated in Tamil version. Every question has been framed both in English and Tamil. Since in this question the Tamil translation has been wrongly made namely, instead of translating 'ethyl benzoate' it has been wrongly translated as 'ethyl acittatin', mark should be awarded to the petitioners.
13.1. The learned Special Government Pleader appearing for the respondents taking note of the Instruction No.10 in the first page of the question paper submitted that if any doubt arises, English version shall be taken final. There is no any spelling mistake, but the word 'ethyl benzoate' has been wrongly translated as 'ethyl acittatin'.
13.2. When 'ethyl benzoate' is wrongly translated as 'ethyl acittatin', the framers of the question have completely misled the candidates in Tamil version. Moreover, some of the candidates who would choose to read the tamil translation of the question would be in my considered view left without any idea and will be put to confusion, therefore, granting of one mark cannot be objected. Hence, I hereby award one mark for this question. Moreover, Tamil Medium students will not be in a position to answer the correct question.
Booklet series 'A' - Question No.44:-
Which of the following shows highest vibration in Raman Spectroscopy?
(A)Nitrogen (B)Flourine (C)Methane (D)Carbon disulphide
14. Mr.Gubendran, Associate Professor, suggested that reading of question No.44 does not properly convey whether it asks vibration frequency or vibration mode. Taking support from pages 112, 115 and 116 of the book namely, ''Fundamentals of Molecular Spectroscopy'' by Colin N.Banwell and Elaine M.Mccash, he stated that there are vibration frequency and vibration mode and without showing clear vibration mode or vibration frequency, the petitioners cannot answer the question.
14.1. Meeting that argument, Dr.S.Arul Antony and Dr. S.Chidambara Vinayagam, Associate Professors, replied that when the words 'highest vibration' in Raman Spectroscopy are worded, the highest vibration is only in frequency, therefore, the student cannot expect the addition of frequency or mode.
14.2. Drawing the notice of this Court to page 99 of the book namely, ''Fundamentals of Molecular Spectroscopy'' by Colin N.Banwell and Elaine M.Mccash, an illustration has been presented namely, 3.5 to say that the question should either have frequency or mode. Although I am inclined to accept the said contention, two of the experts namely, Dr.S.Arul Antony and Dr. S.Chidambara Vinayagam, Associate Professors, submitted that highest vibration itself clearly connotes frequency in Raman Spectroscopy, therefore, going by the majority view of the experts, I am of the view that the respondents have rightly framed this question in which the petitioners cannot have any grievance.
14.3. At this juncture, Mr.Ajmal Khan, learned Senior Counsel for the petitioners submitted that question itself is not precise and clear. May be, the addition of the word 'mode' or 'frequency' after highest vibration would have conveyed clear meaning to the candidates to meet the said question with ease. However, I find the justification given by the respondents are acceptable, hence, there is no error in question No.44.
Booklet series 'A' - Question No.63:-
15. Mr.Gubendran, explaining the framing of the question and also the mistake committed by the question setter stated that when TRB has given (D) as the correct answer, the same cannot be correct. Firstly, the answer given in (D) Angular momentum(Lz) cannot be matched with option (ii), therefore, option (iii) should be properly mentioned and option (ii) is unnecessarily worded.
15.1.Taking support from Table 4.1 at page 106 of the book namely, Atomic Structure and the Chemical Bond including Molecular Spectroscopy by Manas Chanda and page 313 of the book namely, Atkins' Physical Chemistry by Peter Atkins and Julio de Paula namely, it is stated that Angular momentum has to necessarily match with option (ii). Similarly, the Momentum should also match with option (iii).
15.2. Although the learned Special Government Pleader submitted that question No.63 has been rightly framed, I am not inclined to accept the same. The reason is, I could see some substance in the explanation offered by Dr.Gubendran, who is supported with two books mentioned above, therefore, I award one mark for this question.
Booklet series 'A' Question No.72:-
Which is not correctly matched?
(A)Ferromagnetic - Gd, Fe (B)Anti ferromagnetic (below its Tc) - KmnO4 (C)Paramagnetic - Ni, Co (D)Ferrimagnetic - Fe3O4
16. Taking support from the book namely, ''Elements of Analytical Chemistry'' by R.Gopalan, P.S.Subramanian and K.Rengarajan Dr.Chidambaravinayagam and Dr.Arul Antony submitted that option (C) is the correct answer. However, perusal of the following passage from the book namely, ''Advanced Inorganic Chemistry'', Volume-I, by Satya Prakash, G.D.Tuli, S.K.Basu and R.D.Madan namely, ''Examples of paramagnetic substances are Al, Cr, Mn, CuSO4, liq, O2, Fe, Co, Ni, Pt, [Ni (H2O6) Cl2, [Mn (H2O6] Cl2, NO, transition metal oxides (e.g.TiO, Ti2 O3, VO, VO2, CuO etc), transition metal ions etc.'' shows that the petitioners are right in his contention, therefore I grant one mark for this question.
Booklet series 'A' - Question No.79
17. Challenging the framing of question No.79, Dr.Gubendran stated that the answer (C) given by the TRB is not properly worded. 'en' means ethiline diamine, hence, the question itself is incorrect, therefore, it is impossible to find out the correct answer for the wrong question. He has also stated that there is no such formula in chemistry en for electron. However, replying to the same, both the experts namely, Dr.Chidambara Vinayagam and Dr.Arul Antony submitted that 2en means 2 electron or even en is electron. When it is basic and fundamental, any chemistry student can easily without any confusion understand the said question. Adding further, they stated that when (a) has been matched with option (ii) and (b) has been matched with option (i), it goes without saying that (c) has to match with option (iii). I find merit on the said submission. Therefore, I am of the view that TRB have correctly framed this question.
Booklet Series 'A' - Question No.99 Pick out the achiral compound from the following: rPh;ikaw;w Nrh;kk; vJ?
18. This question has been translated in tamil as rPh;ikaw;w instead of rPh;ikj;jd;ikAs;s.
18.1. Mr.VR.Shanmuganathan, learned Special Government Pleader, appearing for the respondents has also shown from the Internet the true meaning of ifuy; means rPh;ikaw;w and achiral means rPh;ikj;jd;ikAs;s.
18.2. Therefore, the question was wrongly framed that can be further justified from the jkpo;ehl;Lg; ghlEhy; fofk;> Chemistry, Higher Secondary, Volume-II, Page No.115 is as follows:
?xU %yf;$W rPh;ikj;jd;ikaw;wjhf (xsp Row;Wk; jd;ikAs;sjhf ,Uf;f) mjd; Gwntsp mikg;Gk;> Mb gpk;g Gwntsp mikg;Gk; Nkw;nghUe;jhj; jd;ikAilajhf ,Uj;jy; mtrpak;. ,j;jifa %yf;$Wfs; 'ifuy;' %yf;$Wfs; vd;W miof;fg;gLfpd;wd.
18.3. Therefore, one mark is awarded.
Booklet Series 'A' - Question-102.
The correct decreasing order of relative resonance energies of following compounds is:
fPo;f;fz;l Nrh;kq;fspd; rhpahd> xg;gPl;L cldpirT Mw;wy;fspd; ,wq;F thpir vJ?
(A) (c) > (b) > (d) > (a) (B) (b) > (a) > (c) > (d) (C) (a) > (b) > (c) > (d) (D) (c) > (d) > (a) > (b)
19. The correct answer given by TRB is 'D'. The reason is, Benzene 36 glories, thiophene 29 glories, pyrrole 21 glories, furan 16 glories.
19.1. Dr.Chidhambaram Vinayagam would explain the answer for this question with the book namely, Modern Organic Chemistry. I agree with the said explanation offered by Dr.Chidhambaram Vinayagam. Hence, I hold that the Question No.99 is rightly framed.
Question No.103:-
The chemical name of Quercetin is:
(A)5, 7 ? Dihydroxy flavonol (B)5, 7, 4' ? Tri hydroxy flavonol (C)5, 7, 3', 4' ? Tetra hydroxy flavonol (D)5, 7, 3', 4', 5' ? penta hydroxy flavonol
20. Challenging the aforesaid question, it is contended on behalf of the petitioners that TRB answer (C) cannot be the correct answer. In support of the same, the following passage at page 801 of the book namely, ''Organic Chemistry Volume-2: Stereochemistry and the Chemistry of Natural Products'' by I.L.Finar, is relied upon which is given as under:-
20.1. The passage at page 2.69 of the book namely, ''Organic Chemistry of Natural Products Volume-II'' by Gurdeep R.Charwal is also relied on which is given as under:-
20.2. Both the experts namely, Dr.Chidambara Vinayagam and Dr.Arul Antony fairly agreeing with the answer given by Dr.Gubendran submitted that the question is to be carefully seen whether the chemical name of Quercetin is 5, 7, 3', 4' ? Tetra hydroxy flavonol. If question No.103 has included Quercetin 3, 3', 4', 5, 7, then the petitioners are right in his contention, therefore, the candidates should have carefully answered only (C) as answer. I find merit in the said submission.
Booklet Series 'A' - Question-110 Find out the incorrect statement with respect to isotopic dilution analysis:
(A) Unknown amount of aureomycin can be calculated using 14 C labelling.
(B) Potassium impurity in tungsten filaments can be determined by 40 K (0.57%).
(C) Chromium content of ruby(51 Cr) and manganese content of tea leaves ( 55 Mn) also be evaluated.
(D) Volume of blood in Human can be determined by 24 Na or 128I or 51 Cr or 51 P.
21. The correct answer is 'C'. The answer options of A, B & D belongs to isotopic dilution analysis.
21.1. Dr.Chidambara Vinayagam, taking support from the book namely, ?Essentials of Nuclear Chemistry? submitted that the incorrect statement with respect to isotopic dilution analysis is answer 'C' namely, Chromium content of ruby (51 Cr). The options A, B, D are the correct statements and the option 'C' is incorrect statement.
22. Before parting with this case, I hereby place on record my appreciation for the services rendered by the experts mentioned above. Accordingly, the respondents are directed to award each one mark to the following questions in Booklet Series 'A' namely, 10, 14, 43, 63, 72 and 99, as per the conclusions reached herein above only in respect of the petitioners. No costs. Consequently, connected miscellaneous petitions are closed.
