17.4 Reactions of side chains
The term aromatic (Greek; aroma means fragrance) was first used for compounds having pleasant odour although the structure was not known. Now the term aromatic is used for a class of compounds having a characteristic stability despite having unsaturation. These may have one or more benzene rings (benzenoid) or may not have benzene ring
(non-benzenoid). Benzenoid compounds include benzene and its derivatives having aliphatic side chains (arenes) or polynuclear hydrocarbons, eg. naphthalene, anthracene, biphenyl etc.
