Question

Identify ‘Z’ in the sequence:

$C_{6}H_{5}NH_{2}\underset{273K}{\overset{\quad NaNO_{2} + HCl\quad}{\rightarrow}}X\overset{\quad CuCN\quad}{\rightarrow}Y\underset{Boil}{\overset{\quad H^{+}/H_{2}O\quad}{\rightarrow}}Z$

• 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)

$C_{6}H_{5}COOH$

Answer 2

: $C_{6}H_{5}NH_{2}\underset{273K}{\overset{\quad NaNO_{2} + HCl\quad}{\rightarrow}}\underset{(X)}{C_{6}H_{5}{\overset{+}{N}}_{2}Cl^{-}}\overset{\quad CuCN\quad}{\rightarrow}$

$\underset{(Y)}{C_{6}H_{5}CN}\underset{boil}{\overset{\quad H^{+}/H_{2}O\quad}{\rightarrow}}\underset{Benzoicacid(Z)}{C_{6}H_{5}COOH}$
