Question

In order to prepare a 1° amine from an alkyl halide with simultaneous addition of one = CH₂ group in the carbon chain, the reagent used as a source of nitrogen is

(a) potassium phthalimide, C₆H₄(CO)₂ N^-K⁺

(b) potassium cyanide, KCN

(c) sodium azide, NaN₃

(d) sodium amide, NaNH₂

Answer 1

Correct option: (b) potassium cyanide, KCN

In order to prepare 1° amine from an alkyl halide with simultaneous addition of one = CH₂ group in the carbon chain, the reagent used as a source of nitrogen is KCN. Chemical transformation can be shown as:
