Question

An organic compound X(molecular formula C6H7O2N) 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 homocydic (C) homocyclic and aromatic (D) heterocyclic and aromatic

Tardigrade Admin · Accepted Answer

For a compound to be aromatic, it must have

(4 n + 2) π

electrons.
Here two double bonds are present,

4 π

electrons are present in the compound. Therefore, it is anti-aromatic.
Homocyclic compounds are ring structures that consist only of carbon atoms within the ring. A nitro group is attached to the ring system as a substituent, so,

C_{6} H_{7} N O_{2}

is homocyclic but not aromatic.
