Ethyl chloride on heating with silver cyanide forms a compound X. The functional isomer of X is.

A

C2H5NCC_{2}H_{5}NC

B

C2H5CNC_{2}H_{5}CN

C

H3CNHCH3H_{3}C - NH - CH_{3}

D

C2H5NH2C_{2}H_{5}NH_{2}

Answer

C2H5CNC_{2}H_{5}CN

Explanation

Solution

C2H5Cl+AgCNC2H5N=CEthylisocyanide(X)+AgClC_{2}H_{5}Cl + AgCN \rightarrow \underset{\begin{aligned} & \text{Ethylisocyanide} \\ & (X) \end{aligned}}{C_{2}H_{5} - N\overrightarrow{=}C} + AgCl

The functional isomer of ethyl isocyanide is ethyl cyanide C2H5CNC_{2}H_{5} - C \equiv N.
