Question
In order to prepare a 1° amine from an alkyl halide with simultaneous addition of one \[\ce{CH2}\] group in the carbon chain, the reagent used as source of nitrogen is ______.
Options
Sodium amide, \[\ce{NaNH2}\]
Sodium azide, \[\ce{NaN3}\]
Potassium cyanide, \[\ce{KCN}\]
Potassium phthalimide, \[\ce{C6H4 (CO)2N– K+}\]
Solution
In order to prepare a 1° amine from an alkyl halide with simultaneous addition of one \[\ce{CH2}\] group in the carbon chain, the reagent used as source of nitrogen is Potassium cyanide, \[\ce{KCN}\].
Explanation:
Potassium cyanide, as cyanide on reduction with sodium metal in alcohol, produces amine with increased carbon atoms.
\[\ce{R - X ->[KCN - KX] R - CN ->[Na/C2H2OH] R - CH2NH2}\]
