Molecular orbit ( M O T ) theory is more accurate theory than valence bond theory . In molecular orbital theory,we imagine that electronic orbitals cover the whole molecule and are not localised around one atom. Molecular orbital theory is based on wave superposition principle. Waves with same phase will interfere constructively and increase their amplitude. While opposite phases interfere destructively to decrease their amplitude. Concept introduction: From above it becomes clear that no of atomic orbital is equal to molecular orbital.

Answer 1

Question

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.
