हिन्दीIdentify the major product C formed in the following reaction sequence: \( \text{CH}_3-\text{CH}_2-\text{CH}_2-\text{I} \xrightarrow{\text{NaCN}} \text{A} \xrightarrow[\text{Partial hydrolysis}]{\text{OH}^-} \text{B} \xrightarrow{\text{NaOH} / \text{Br}_2} \text{C (major)} \)
Correct answer · Option 3
propylamine
Explanation
Product A is butanenitrile (\( \text{CH}_3\text{CH}_2\text{CH}_2\text{CN} \)), which on partial hydrolysis yields butanamide (Product B, \( \text{CH}_3\text{CH}_2\text{CH}_2\text{CONH}_2 \)). Hofmann bromamide degradation of butanamide yields propylamine (Product C, \( \text{CH}_3\text{CH}_2\text{CH}_2\text{NH}_2 \)).
