Q. Which of the following reactions does not yield an amine?
JIPMER
JIPMER 2015
Amines
A
$R - X + NH_3 \xrightarrow{ 373\, K}$
11%
B
$R - CH = NOH + [H]\xrightarrow[C_2H_5OH]{Na}$
26%
C
$R - CN + H_2O \xrightarrow{H^+}$
52%
D
$R - CONH_2 +4[H] \xrightarrow{LiAlH_4}$
11%
Solution:
$R - X + NH_3 \xrightarrow{ 373\, K} R - NH_2 + HX $
$R - CH = NOH + 4 [H] \xrightarrow[C_2H_5OH]{Na}$
$ RCNH_2NH_2 + H_2O$
$R - CONH_2 +4[H] \xrightarrow{LiAlH_4}RCNH_2NH_2 + H_2O$
But, $R - CN + 2H_2O \xrightarrow{H^+} R COOH + NH_3$
