Molecular orbitals energy level diagram consists of

Options

A. bonding molecular orbitals
B. antibonding molecular orbitals
C. nonbonding molecular orbitals
D. molecular orbitals in order of increasing energy

Answer

D

Explanation

In order to write the electron configuration of any molecule, we must first arrange the molecular orbitals that are formed in the molecule in order of increasing energy. Once the order, i.e., MO energy level diagram is known, we can use the rules (used in atomic structure) to guide us in filling these molecular orbitals with electrons.
