Question: 70: Match List-I with List-II.
| List – I (Products formed) | List – II (Reaction of carbonyl compound with) |
|---|---|
| (a) Cyanohydrin | (i) \mathrm{NH}_{2}\mathrm{OH} |
| (b) Acetal | (ii) \mathrm{RNH}_{2} |
| (c) Schiff’s base | (iii) alcohol |
| (d) Oxime | (iv) HCN |
Choose the correct answer from the options given below
(1) (a) – (i), (b) – (iii), (c) – (ii), (d) – (iv)
(2) (a) – (iv), (b) – (iii), (c) – (ii), (d) – (i)
(3) (a) – (iii), (b) – (iv), (c) – (ii), (d) – (i)
(4) (a) – (ii), (b) – (iii), (c) – (iv), (d) – (i)
Answer: Option (2)
Explanation:
Cyanohydrins are formed when a carbonyl compound reacts with hydrogen cyanide HCN,
producing a \mathrm{C(OH)(CN)} group.
Acetals are formed by the reaction of aldehydes or ketones with alcohols in the presence of acid.
Schiff’s bases are formed when a carbonyl compound reacts with a primary amine
\mathrm{RNH}_{2}, resulting in an imine.
Oximes are formed when a carbonyl compound reacts with hydroxylamine
\mathrm{NH}_{2}\mathrm{OH}.
Thus, the correct matching is (a) – (iv), (b) – (iii), (c) – (ii), (d) – (i).
