Answer 1

Answer:

canonical structures are equivalent than if canonical structures are non-equivalent. Molecule is aromatic than if molecule is not aromatic. more number of π-bonds are involved in resonance than less number of π-bonds are involved. Resonance with 2p-2p overlapping than resonance with 3p-2p overlapping.
