Why Benzene ring is hexagonal?
This is because if it could exist in long chain form then the addition reactions of H2 and Cl2 should also b obeyed by it.But 3 molecules of each above react with 1 of benzene.But the chained structure goes toward 4 molecules of each.This predicts that benzene is not chain molecule i.e Aliphatic.The carbon atom’s hybridized orbitals overlap in such a way that the internal angle is 120 degree.It should notice that internal angle of hexagon is same.So it exists in such shape.Its my opinion.
