No Negative marking forwrong answer.• In section -IV (8 Ques.) of each paper +4 marks will be given for correct answer & –1 mark for wrong answer.CHEMISTRYSECTION – IStraight Objective TypeThis section contains 4 multiple choice questions. Eachquestion has 4 choices (A), (B), (C) and (D), out ofwhich ONLY ONE is correct.The correct structures of 'A' and 'B' are,respectively–(A) CH2 =CH COOH ;CH=CHCOOHCOOH(B)CH 2 =C; CH=CH–COOH1.NOBr ProductNH 2The main product is –+ Enantiomer(A)Br(B)+ EnantiomerBrBr(C)+ EnantiomerNO(D)+ Enantiomer(C) CH=CHCOOH ; CH 2 =CH COOH(D) CH=CH–COOH ;C=CH 2COOH3. If H-He undergoes dissociation, which of thefollwoing product most expected to occur –2HHe products(A) He 2 + 2H (B) H 2 + 2He(C) D 2 + He 2 (D) 2H + 2He4. 100 ml solution (I) of buffer containing 0.1(M) HAand 0.2 (M) A – , is mixed with another solution (II) of100 ml containing 0.2(M) HA and 0.3(M) A – .Aftermixing what is the pH of resulting solution ?( GivenpK a of HA = 5)(A) 5 – log 5/3 (B) 5 + log 5/3(C) 5 + log 2/5 (D) 5 – log 5/22. There are two isomeric carboxylic acids– 'A' and 'B'C 9 H 8 O 2 . reacts with H 2 /Pd giving compounds,C 9 H 10 O 2 . 'A' gives a resolvable product and 'B' givesa non-resolvable product. Both isomers could byoxidised to PhCOOH.SECTION – IIMultiple Correct Answers TypeThis section contains 5 multiple correct answer(s) typequestions. Each question has 4 choices (A), (B), (C) and(D), out of which ONE OR MORE is/are correct.XtraEdge for IIT-JEE 62APRIL 2010

In the given table types of H bonds and some H bondenergies are given and other H bond energies are notgiven. You are to perdit the unknown H-bondenergies.Types of H-bonds H-bond energies in KJ/mol(I) F – H …….. O –F – H …….. F 30(II) O – H …….. O –O – H …….. F 15(III) F – H …….. F – –(IV) N – H …….. N –Correct prediction are –(A) H-bond energy for (I) may be 20 kJ/mol(B) H-bond energy for (II) may be 25 kJ/mol(C) H-bond energy for (III) may be 113 kJ/mol(D) H-bond energy for (IV) may be 12 kJ/mol8. During conductance measurement of an electrolytebased on the wheatstone bridge principle alternatingcurrent is used because direct current produces –(A) polymerisation(B) Ionisation(C) Electrolysis resulting in the chnge ofconcentration and in consequencae the resistance(D) Polarisation at the electrodes resulting in thechange of resistance9. Consider the cell :Ag | AgCl (s) | KCl (1M) | Hg 2 Cl 2 (s) | Hg (l) | Pt. Thecell potential :(A) increases on increasing concentration of Cl – ions(B) decreases on decreasing concentration of Cl – ions(C) is independent of concentration of Cl – ions(D) is independent of amounts of AgCl (s) andHg 2 Cl 2 (s)SECTION – IIIMatrix - Match TypeThis section contains 2 questions. Each questioncontains statements given in two columns, which haveto be matched. The statements in Column I are labeledA, B, C and D, while the statements in Column II arelabeled p, q, r, s and t. any given statement in Column Ican have correct matching with ONE OR MOREstatements (s) in column II. The appropriate bubbledcorresponding to the answers to these questions have tobe darkened as illustrated in the following example :If the correct matches are A – p, s and t; B – q and r;C – p and q; and D – s and t; then the correctdarkening of bubbles will look like the following.p q r s tABCDppqq10.
