MCQ
Ethyl chloride on heating with silver cyanide forms a compound $X$ . The functional isomer of $ X$ is
- A${C_2}{H_5}CN$
- ✓${C_2}{H_5}NC$
- C${H_3}C - NH - C{H_3}$
- D${C_2}{H_5}N{H_2}$
✓
Answer
Correct option: B.
${C_2}{H_5}NC$
b
(b)${{C}_{2}}{{H}_{5}}Cl+AgCN\to \underset{\begin{smallmatrix}
\text{Ethyl}\,\,\text{isocyanide} \\
\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\text{(X)}
\end{smallmatrix}}{\mathop{{{C}_{2}}{{H}_{5}}-N\vec{=}\,C}}\,+AgCl$
(b)${{C}_{2}}{{H}_{5}}Cl+AgCN\to \underset{\begin{smallmatrix}
\text{Ethyl}\,\,\text{isocyanide} \\
\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\text{(X)}
\end{smallmatrix}}{\mathop{{{C}_{2}}{{H}_{5}}-N\vec{=}\,C}}\,+AgCl$
The functional isomer of ethyl isocyanide is ethyl cyanide
${C_2}{H_5} - C \equiv N$
