Hi

πbackbonding, also called π backdonation, is a concept from chemistry in which electrons move from an atomic orbital on one atom to an appropriate symmetry antibonding orbital on a π-acceptor ligand.
Antiaromaticityis a characteristic of a cyclic molecule with a π electron system that has higher energy due to the presence of 4n electrons in it. Unlike aromaticcompounds, which follow Hückel's rule ([4n+2] π electrons) and are highly stable,antiaromatic compoundsare highly unstable and highly reactive.
