IIT JEE 2009 Chemistry Paper2 Code 1 Solutions

Matrix Match Type

10.    Match each of the compounds given in Column I with the reaction(s), that they can undergo given in Column II.

Column I		Column II
(A)		(p)	Nucleophilic Substitution
(B)		(q)	Elimination
(C)		(r)	Nucleophilic addition
(D)		(s)	Esterification with acetic anhydride
		(t)	Dehydrogenation

Sol.   (A - p, q, t), (B - p, s, t), (C - r, s), (D - p)

11.    Match each of the reactions given in Column I with the corresponding product(s) given in Column II.

Column I		Column II
(A)	Cu + dil HNO3	(p)	NO
(B)	Cu + conc. HNO3	(q)	NO2
(C)	Zn + dil HNO3	(r)	N2O
(D)	Zn + conc. HNO3	(s)	Cu(NO3)2
		(t)	Zn(NO3)2

Sol.   (A - p, s), (B - q, s), (C - r, t), (D - q, t)

         Below are the reactions of the corresponding reactants-

        3Cu + dil. 8HNO₃ --> 3Cu(NO₃)₂ + 4H₂O + 2NO

        Cu + conc. 4HNO₃ --> Cu(NO₃)₂ + 2H₂O + 2NO₂

        4Zn + dil. 10HNO₃ --> 4Zn(NO₃)₂ + 5H₂O + N₂O

        Zn + conc. 4HNO₃ --> Zn(NO₃)₂ + 2H₂O + 2NO₂
