Which one of the following is an example of heterocyclic aromatic compound?
Answer: E
The heterocyclic aromatic compound is Furan.
A heterocyclic compound has at least one atom other than carbon in its ring. Furan is a five-membered ring of four carbon atoms and one oxygen atom. It is aromatic: the four carbon p electrons and one lone pair from oxygen give a planar ring of six delocalised pi electrons, satisfying Huckel's (4n + 2) rule with n = 1.
Phenol, aniline and toluene are aromatic but homocyclic: their ring is benzene, made of carbon only, and the O, N or CH3 is a substituent outside the ring. Naphthalene has two fused benzene rings, again all carbon.
