How to add a nitrile group to benzene

NettetFirstly, you cant go ethane to propene, it should be propane. Chemically, you can do it by following steps: halogenate with C l in UV. then use K C N to make nitrile - it will replace C l. hydrolyse it using K O H. then it will be a carboxylic acid. reduce it using L i A l H X 4 and then, you have got propane.
