Detailed Solution

For a compound to be aromatic or anti-aromatic, it must be cyclic, planar, and fully conjugated. Once it satisfies these conditions, then we look at the number of conjugated electrons as per the Huckel's rule. If it is (4n+2) π electrons, it is aromatic, and if it is 4n π electrons, it is anti-aromatic. image
