Question
Which statement is not true of molecular orbitals?
A)The number of molecular orbitals formed is always equal to the number of atomic orbitals combined.
B)A molecular orbital can accommodate up to two electrons.
C)When electrons are added to orbitals of the same energy, the most stable arrangement is predicted by Hund's rule.
D)Low-energy molecular orbitals fill before high-energy molecular orbitals fill.
E)Antibonding molecular orbitals are higher in energy than all of the bonding molecular orbital
Explanation / Answer
the postulates of MO theory
answer is E . because not always antibonding mos are high in energy than bonding MOs . Antibonding orbitals will be in hgher in energy than corresponding bonding Mos.and lower energy orbitals
