(a) Interpretation: The relative energies of the π molecular orbitals for allyl radical having three π electrons are to be predicted. Concept introduction: Hückel theory deals with the conjugated systems. In this theory, the π and σ bonds are treated separately. It states that the σ bonds form the overall structure of the molecule and the π bonds spread out over the carbon atoms. In Hückel approximation, the π orbitals are assumed to be the combination of the atomic orbitals of the carbon atoms which are involved in conjugation of π bonds.
