Solution

\[\ce{\underset{(Ethyl alcohol)}{CH3CH2OH} ->[red 'P'][Br2] \underset{(A)}{\underset{(Ethyl bromide)}{CH3 - CH2 - Br}}}\]

\[\ce{\underset{(A)}{\underset{(Ethyl bromide)}{CH3 - CH2 - Br}} ->[KCN][alc.] \underset{(B)}{\underset{(Ethyl cyanide)}{CH3 - CH2 - CN}}}\]

\[\ce{\underset{(B)}{\underset{(Ethyl cyanide)}{CH3 - CH2 - CN}} ->[LiAH4][Ether] \underset{(C)}{\underset{(Propan-1-amine)}{CH3 - CH2 - CH2 - NH2}}}\]
