Question

In the reaction sequence

$\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{Br} \stackrel{\mathrm{AgCN}}{\rightarrow}(\mathrm{X}) \stackrel{\mathrm{H}_2 \mathrm{O} / \mathrm{OH}^{-}}{\rightarrow}(\mathrm{Y})$

(Y) will be

• A. $CH_{3}-CH_{2}-CH_{2}-NH_{2}$
• B. $CH_{3}-CH_{2}-NH_{2}$
• C. $CH _{3}-\left( CH _{2}\right)_{2}- CH _{2}- NH _{2}$
• D. $CH _{3}-\left( CH _{2}\right)_{3}- CH _{2}- NH _{2}$

Answer 1

Answer: (A)

Here X is propyl isocyanide and Y is propyl amine

$CH_{3}-CH_{2}-CH_{2}-Br\overset{A g C N}{ \rightarrow }\underset{\left(\right. X \left.\right)}{C H_{3} - C H_{2} - C H_{2} - \overset{\oplus}{N} \equiv \overset{-}{C}}\overset{H_{2} O / \overset{-}{O} H / \Delta }{ \rightarrow }\underset{\left(\right. Y \left.\right)}{C H_{3} - C H_{2} - C H_{2} - N H_{2}}+HCOOH$
