Question

Mention some differences between BMO and ABMO

Answer 1

Bonding Molecular Orbitals

1. Formed by additional overlap

2. More Stable

3. Energy is less

4. Electron density between the bonded nuclei higher

Antibonding Molecular Orbitals

1. Formed by subtraction overlap
2. Less stable
3. Energy is greater
4. Electron density between the bonded nuclei is lower.

Answer 2

Answer:

BMO:-

• Here wave function are added.
• Electron density is more
• attraction is present
• Constructive interference
• Doesn't have nodal plane
• Energy of BMO is less
• Electron placed in a BMO stabilise a molecule.

ABMO:-

• Wave function is subtracted
• Electron density is less
• repulsion is present
• Destructive interference
• Have nodal plane between nuclei of bonded atom
• Energy is high
• Destabilizes the molecule
