In order to prepare a 1^(@) amine from an alkyl halide with simultaneous addition of one CH_(2)group in the carbon chain, the reagent used as source of nitrogen is…..

Answer»

Sodium AMIDE (`NaNH_2`)
Sodium azide (`NaN_3`)
POTASSIUM cyanide (KCN)
Potassium PHTHALIMIDE `[C_6 H (CO)_2N^(-) K^(+) ]`.

Solution :Cyanides on reduction gives `1^@`amines with a `CH_2`group, i.e.,
` R - X underset(-KX ) overset("KCN" )TOR -CNoverset(Na//C_2 H_5OH) to R -CH_2 NH_2`
