Question

Identify 'A' and 'B' in the following conversions.

\[\ce{CH3 - I ->[Alc. KCN][\Delta] A ->[Na/C2H5OH] B}\]

Options

• A = propan-1-amine, B = Ethanamine

• A = Methyl cyanide, B = Ethanamine

• A = Ethyl cyanide, B = Butan-1-amine

• A = Methyl cyanide, B = Propan-1-amine

Answer 1

A = Methyl cyanide, B = Ethanamine

Explanation:

\[\ce{\underset{lodomelthane}{CH3 - I} ->[Alc. KCN][\Delta] \underset{\underset{(A)}{Methyl cyanide}}{CH3CN} ->[4{[H]}][Na/C2H5OH] \underset{\underset{(B)}{Ethanamine}}{CH3CH2NH2}}\]
