An organic compound X (molecular formula \[{{C}_{6}}{{H}_{7}}{{O}_{2}}N\]) has six carbon atoms in a ring system, two double bonds and a nitro group as substituent, X is :

A) Homocyclic but not aromatic

B) Aromatic but not homocyclic

C) Homocyclic and aromatic

D) Heterocyclic and aromatic

Correct Answer: A

Solution :

[a] Hence it is homocyclic (as the ring system is made of one type of atoms, i.e. carbon) but not aromatic. As it does not have \[(4n+2)\pi \] electron required for aromaticity.
