MCQ
Which of the following reactions does not yield an amine
  • A
    $RX + N{H_3}\xrightarrow{{}}$
  • B
    $RCH = NOH + [H]\mathop {\xrightarrow{{Na}}}\limits_{{C_2}{H_5}OH} $
  • ✓
    $RCN + {H_2}O\xrightarrow{{{H^ + }}}$
  • D
    $RCON{H_2} + 4H\xrightarrow{{LiAl{H_4}}}$
✓

Answer

Correct option: C.
$RCN + {H_2}O\xrightarrow{{{H^ + }}}$
c
(c) $R - CN + {H_2}O\xrightarrow{{{H_2}O/{H^ + }}}RCOOH + N{H_3}$

It yield amine when reduced as -

$R - CN + {H_2} \to R - C{H_2} - N{H_2}$
