Question

Mark the correct route of the conversion of $p$-chloroaniline to $p$-chlorobenzylamine.

	(i)	(ii)	(iii)
(a)	Alkylation	$KCN$	$H_2/Pt$
(b)	Diazotisation	$CuCN$	$H_2/Pt$
(c)	Oxidation	$H_2/Pt$	Hydrolysis
(d)	Diazotisation	$H_{2}O/H^{+}$	$Sn/HCl$

• A. a
• B. b
• C. c
• D. d

Answer 1

Answer: (B)

$P$-chloro aniline is diazotised to diazosalt, which reacts with $CuCN$ (sandmayer's reaction) to form $p$-chloro cyanobenzene, which in turn reacts with $H_2/Pt/Ni$ to form $p$ chloro benzylamine.
