In order to prepare a1º1ºamine from an alkyl halide with simultaneous addition of one CH2CH_{2} group in the carbon chain, the reagent used as source of nitrogen is ______.

A

Sodium amide NaNH3NaNH_{3}

B

Sodium azide, NaN3NaN_{3}

C

Potassium cyanide KCN

D

Potassium phthalimide, C6H4(CO)2N−K+C_{6}H_{4}(CO)_{2}N^{-}K^{+}

Answer

Potassium cyanide KCN

Explanation

Solution

:

R−X→KCNR−CN→Na/C2H5OHR−CH2NH2R - X\overset{\quad KCN\quad}{\rightarrow}R - CN\overset{\quad Na/C_{2}H_{5}OH\quad}{\rightarrow}R - CH_{2}NH_{2}
