Among the given organic compounds, the total number of aromatic compounds is

Step-by-step solution

Huckel’s rule states, for a compound to be aromatic, the compound should be planar, cyclic, and should have ( 4 n + 2 ) π electrons that should be in continuous delocalization or an uninterrupted cyclic pi-electron cloud should be there. Here n= 0 , 1 , 2 … So if we put n= 0 , we get 2 π electrons If we put n= 1 , we get 6 π electrons If we put n= 2 , we get 10 π electrons and so on. Compound (A) is not aromatic due to presence of sp 3 carbon between the rings. Hence the compounds,B,C and D are Aromatic as they hav
