Question

How will you prepare propan-1-amine from butane nitrile?

Answer 1

Preparation of propan-1-amine from butane nitrile:

Butane nitrile was treated with acid hydrolysis followed by Hoffmann’s bromamide degradation gives propan-1-amine.

\[\ce{\underset{(Butane nitrile)}{CH3 - CH2 - CH2 - CN} ->[H^+/H2O] \underset{(Butanamide)}{CH3 - CH2 - CH2 - CINH2} ->[Br2/KOH] \underset{(propan-1-amine)}{CH3 - CH2 - CH2 - NH2}}\]
