- C( B ) , ( C ) and ( D ) only
- D( A ) , ( B ) and ( C ) only
Correct answer
B. ( B ) and ( C ) only
Step-by-step solution
Aromatic compounds are considered as the compound which contains a conjugated planar ring system with delocalized pi-electrons cloud located at alternate double bond and single bond. For a compound to be aromatic it should follow Huckel’s rule which says that the compound should satisfy 4 n + 2 π electrons. For Aromaticity, full conjugation of ( 4 n + 2 ) π electrons should be there in closed ring. (A) Non-Aromatic (B) Aromatic (C) Aromatic (D) Anti-Aromatic
