Question

Identify $Z^{\prime}$ in the sequence:
$C_{6}H_{5}NH_{2}\xrightarrow[{273K}] {NaNO_{2}+HCl} X \xrightarrow{CuCN} Y \xrightarrow[{Boil}]{ H^{+}/H_{2}O} Z $

• A. $C _{6} H _{5} CN$
• B. $C _{6} H _{5} CONH _{2}$
• C. $C _{6} H _{5} COOH$
• D. $C _{6} H _{5} CH _{2} NH_{2}$

Answer 1

Answer: (C)

$C _{6} H _{5} NH _{2} \xrightarrow[273\, K]{ NaNO _{2}+ HCl } C _{6} H _{5} N _{2}^{+} Cl ^{-} \xrightarrow{ CuCN } $

$C _{6} H _{5} CN \xrightarrow[\text{ Boil }]{ H ^{+} /H _{2} O } C _{6} H _{5} COOH $
