Electrophilic Substitution Reactions
in Aldehydes and Ketones
Electrophilic Substitution Reaction
Aromatic aldehydes and ketones undergo electrophilic substitution reactions such as nitration, sulphonation and halogenation. Since the aldehydic group (-CHO) and ketonic group (-COR or -COAr) are electron-withdrawing, they are deactivating and m-directing.
Nitration
Sulphonation
Conversion
Convert benzene to m-nitroacetophenone.
