The concept of molecular orbital theory in dealing with the resonance concept of benzene and carbonate ion has to be discussed. Concept Introduction: Molecular orbital theory: During the formation of bond, the atomic orbitals of individual atom will combine together to form equal number of molecular orbital. These orbitals are arranged in the order of increasing energy level, while in case of valence bond theory , the individual atomic orbital will directly involve in bond formation. Resonance is the phenomenon of delocalization of pi- electrons through conjugation. The aromaticity in benzene means the extraordinary stability of benzene. The extraordinary stability means the resonance property of benzene.

Solution Summary: The author explains the concept of molecular orbital theory in dealing with the resonance concept in benzene and carbonate ion.
Definition Definition Theory that explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. VBT gives a quantum mechanical approach to the formation of covalent bonds with the help of wave functions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.

Interpretation Introduction
Interpretation: The concept of molecular orbital theory in dealing with the resonance concept of benzene and carbonate ion has to be discussed.
Concept Introduction:
Molecular orbital theory:
During the formation of bond, the atomic orbitals of individual atom will combine together to form equal number of molecular orbital. These orbitals are arranged in the order of increasing energy level, while in case of valence bond theory, the individual atomic orbital will directly involve in bond formation.
Resonance is the phenomenon of delocalization of pi- electrons through conjugation. The aromaticity in benzene means the extraordinary stability of benzene. The extraordinary stability means the resonance property of benzene.
