Question

How many molecular orbitals are there?

Answer 1

1. There are two types of molecular orbitals:
2. Bonding molecular orbitals that are associated with less energy and Antibonding molecular orbitals which have high energy associated with the atoms.
3. The total atomic orbitals present in a molecule combine together to form molecular orbitals.
4. Thus, ${\mathrm{H}}_2$ has two atomic orbitals as it contains two molecules of Hydrogen.
5. Hence, the molecular orbitals are directly related to atomic orbitals.
