On the basis of aromaticity theory, the compounds A and B are different and the compounds C and D are the same is to be stated. Concept introduction: If a compound is aromatic then it has to follow certain rules. A compound that is cyclic, planar, completely conjugated and follows Huckel’s rule is classified as an aromatic compound. Aromatic compounds follow Huckel’s rule of ( 4 n + 2 ) π electrons. The stability of a compound depends upon the number of resonating structures. If a compound is antiaromatic it has some characteristics features such as they are cyclic, nonplanar, completely conjugated compounds. They do not follow Huckel’s ( 4 n + 2 ) π rule. They have 4 n π electrons. They are highly unstable and highly reactive. They change their shape to avoid instability.
