Chemistry - CHEMICAL BONDING Question with Solution | TestHub
According to MOT (Molecular Orbital Theory), the molecular orbitals are formed by mixing of atomic orbitals through LCAO (linear combination of atomic orbitals). The correct statement(s) about molecular orbitals is/are
Statement (a) : bonding molecular orbitals are formed by addition of wave-functions of atomic orbitals
Statement (b) : anti-bonding molecular orbitals are formed by subtraction of wave-functions of atomic orbitals
Statement (c) : non-bonding molecular orbitals do not take part in bond formation because they belong to inner shells
Statement (d) : anti-bonding molecular orbitals provide stability to molecules while bonding molecular orbitals make the molecules unstable.
Options:
Answer:
Solution:
Bonding M.O. stabilizes molecule, as maximum electron density is found between nuclei of the bonded atom and maximum attraction between them. Antibonding MO destabilizes as minimum electron density is found between nuclei of the bonded atom]
