उत्तर १
\[\ce{\underset{Ethanol}{CH3 - CH2 - OH} ->[red P/Br2] \underset{Bromoethane}{CH3 - CH2 - Br} ->[KCN, aq{.} ethanol]\underset{Propanenitrile}{CH3 - CH2 - CN}}\]
उत्तर २
\[\ce{\underset{Ethanol}{CH3CH2OH} ->[P/I2, \Delta] \underset{Iodoethane}{CH3CH2I} ->[KCN/EtOH-H2O][nucleophilic substitution] \underset{Propanenitrile}{CH3CH2CN}}\]
