FAQs on Molecular Orbital Theory Video Lecture - Chemistry Class 11 - NEET

1. What is molecular orbital theory?
Ans. Molecular orbital theory is a model that explains the bonding and properties of molecules based on the concept of molecular orbitals. It describes how atomic orbitals combine to form molecular orbitals, which are regions of space where electrons are most likely to be found.
2. How does molecular orbital theory differ from valence bond theory?
Ans. In molecular orbital theory, all the atomic orbitals of the bonding atoms are combined to form molecular orbitals, whereas in valence bond theory, only the overlapping atomic orbitals are considered. Molecular orbital theory provides a more comprehensive description of the electronic structure and properties of molecules.
3. What are bonding and antibonding molecular orbitals?
Ans. Bonding molecular orbitals are formed when atomic orbitals combine in-phase, resulting in a lower energy and increased electron density between the bonding atoms. Antibonding molecular orbitals are formed when atomic orbitals combine out-of-phase, resulting in a higher energy and decreased electron density between the bonding atoms.
4. How does molecular orbital theory explain the bond order?
Ans. The bond order is a measure of the stability and strength of a chemical bond. In molecular orbital theory, the bond order is determined by the difference between the number of bonding and antibonding electrons. A higher bond order indicates a stronger and more stable bond.
5. Can molecular orbital theory explain the properties of complex molecules?
Ans. Yes, molecular orbital theory can be applied to complex molecules to understand their electronic structure and properties. By considering the combination of atomic orbitals in the molecule, molecular orbital theory can provide insights into various properties such as bond lengths, bond angles, and reactivity.
