Which of the following is incorrect regarding the MO theory?

Options

A. The number of molecular orbitals formed is always equal to the number of atomic orbitals combined.
B. The more stable the bonding molecular orbitals, the less stable the corresponding antibonding molecular orbital.
C. In a stable molecule, the number of electrons in bonding molecular orbitals is always equal to that in antibonding molecular orbitals.
D. Like an atomic orbital, each molecular orbital can accommodate up to two electrons with opposite spins in accordance with the Pauli exclusion principle.

Answer

C

Explanation

In a stable molecule, the number of bonding electrons is always greater than the number of antibonding electrons.
