Which of the following compounds is not aromatic?

Correct answer

Step-by-step solution

Cyclic conjugation Lone pair involved in aromaticity Having = 6 π e - Aromatic Cyclic conjugation and by Huckel rule = 6 π e - So aromatic Cyclic conjugation 6 π e - Cyclic conjugation lp of - N is involved in delocalization Having = 6 π e - Aromatic Cyclic conjugation and by Huckel rule = 4 π e - So ,Anti-aromatic
