Answer:
Correct Answer: 32. $A \rightarrow p, q, s, t ; B \rightarrow p, s, t ; C \rightarrow p ; D \rightarrow r$
Solution:
| Column I | Column II | |
|---|---|---|
| (A) | $CH _3 CH _2 CH _2 CN$ : | Gives amine with $Pd-C / H _2$ Gives aldehyde with $SnCl _2 / HCl$ Gives amide with diisobutyl- aluminium hydride. Gives carboxylic acid on alkaline hydrolysis. |
| (B) | $\underset{\text { ester }}{CH _3 CH _2 OCOCH _3:}$ | Reduced to alcohol with $Pd-C / H _2$ Reduced with diisobutylaluminium hydride into aldehyde. Undergo alkaline hydrolysis. |
| (C) | $CH _3 CH=\underset{ }{CHCH} CH _2 OH$ | Reduced to butanol when treated with $Pd-C / H _2$. |
| (D) | $CH_3CH_2CH_2CH_2NH_2$ | A primary amine, gives carbylamine test. |
