Answer:
Molecular Orbital Theory
According to this theory, the atomic orbitals combine to form the molecular orbitals. The number of molecular orbitals formed is equal is the number of atomic orbitals involved. According to this theory.
Formation of Molecular Orbitals
Linear Combination of Atomic Orbitals (LCAO)
The formation of molecular orbitals can be explained by the linear combination of atomic orbitals. Combination takes place either by addition or by subtraction of wave function as shown below.
Linear Combination of Atomic Orbitals (LCAO)
Linear Combination of Atomic Orbitals (LCAO)
The molecular orbital formed by addition orbitals is called bonding molecular orbital while molecular orbital formed by subtraction of atomic orbitals is called antibonding molecular orbital.
Conditions for the combination of atomic orbitals:
The combining atomic orbitals must have almost equal energy.
The combining atomic orbitals must have same symmetry about the molecular axis.
The combining atomic orbitals must overlap to the maximum extent.
