A compound with molecular formula C(4)H(...

A compound with molecular formula `C_(4)H_(4)O` has all the four carbon atoms and the oxygen atom in the ring. It also has two double bonds. The compound is

A

Homocyclic and aromatic

B

Heterocyclic and aromatic

C

Homocyclic but not aromatic

D

Heterocyclic but not aromatic

Text Solution

Verified by Experts

The correct Answer is:
B

Furan is heterocyclic and aromatic. Here O is `sp^(2)` hybridised. One lone pair is present in the unhybridised orbital, while the other is present in hybridised `sp^(2)`-orbital. The lone pair present in the unhybridised p-orbital takes part in `ppi-ppi` bonding. Thus there are six `pi`-electrons and as such it is aromatic.
