Question

How are bonding molecular orbitals and antibonding molecular orbitals formed?

Open in App

Solution

Hi,

Bonding Molecular orbital : The molecular orbitals formed by the additive effect of atomic orbitals is called bonding molecular orbital.

Antibonding molecular orbital : The molecular orbitals formed by the subtractive effect of atomic orbitals is called bonding molecular orbital.

Diference between Bonding Molecular orbital and Antibonding molecular orbital :

Bonding Molecilar orbital(BMO)
Anti bonding Molecular orbital(ABMO)

1. BMO has less energy and more stable compared to the parent atomic orbital.
ABMO has more energy and more stable

compared to the parent atomic orbital.

2. In BMO the possibility of finding electrons are maximum. In ABMO the possibility of finding
electrons are minimum.

Q. According to MOT, two atomic orbitals overlap resulting in the formation of molecular orbitals. Number of atomic orbitals overlapping together is equal to the molecular orbital formed. The two atomic orbital thus formed by LCAO (linear combination of atomic orbital) in the same phase or in the different phase are known as bonding and antibonding molecular orbitals respectively. The energy of bonding molecular orbital is lower than that of the pure atomic orbital by an amount
