Question

How is benzenoid different from non benzenoid compounds

Answer 1

Non benzenoid aromatic compound are chemical compounds with conjugated pi-electron system with ring of 5 to 7 carbon atoms. They exhibit aromaticity due to alternate pi-bonds in the molecule. They do not have benzene ring therefore called as non-benzenoid compounds. The chemical reactions of these compounds are like benzenoid compounds only.

Benzenoid compounds have at least one benzene ring in the molecule whereas non-benzenoid compounds are aromatic compounds with conjugated pi-system but do not benzene ring.

Answer 2

Answer:

Aromatic compounds are of two types:

Benzenoids: These compounds contain atleast one benzene ring in their structure

eg. Benzene, benzaldehyde, benzoic acid, naphthalene, anthracene, etc.

Non-benzenoids: These compounds do not contain any benzene rings in their structure

eg. Furan, thiophene, pyridine, etc.
