A compound is said to be aromatic if it satisfies the following conditions simultaneously & It is cyclic @ It is planar. Presence of spt hybridised carbon in the system generally imparts plawarity . (in It exclubits continuous dilocalisation of a lutrons It should follow Huckel's rule that is it should have An+2) number of delocalised I electrons where n=0,1,2,3.... not This compound because it does not &a elutrons. is follow an aromatic compound Huded's rule.

The because it compound has This compound is aromatic compound. It is wyclic and planar. It obuys Huckel's rule it has 6a-eletrons. as Thus the compounds ② and ③ are aromatic
