Why the shape of benzene is hexagonal why not square rectangular?

Answer 1

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.

Answer 2

The benzene molecule is based on 6 carbon atoms linked together in a closed chain. Each bond is of the same strength and therefore of the same length. You cannot get 6 points that are symmetrically placed on a square or rectangle.

Answer 3

The hexagonal structure of benzene is due to its alternating single and double bonds between carbon atoms, resulting in a stable and planar ring. A square or rectangular structure would not allow for efficient overlap of p-orbitals, which is essential for the aromatic stabilization of benzene.
