Which one of the following statements regarding molecular orbital theory is correct?
A) Two bonding orbitals and two antibonding orbitals are formed from one atomic orbital on each of two atoms.
B) p atomic orbitals cannot form $\sigma$molecular orbitals.
C) A 2s$\sigma$ orbital has a higher energy than a 2s$\sigma$* orbital.
D) Only pi molecular orbitals can be formed from p atomic orbitals.
E) s atomic orbitals can only form sigma molecular orbitals.

Question

Quizplus · Accepted Answer

s atomic orbitals can only form sigma molecular orbitals because they are spherically symmetric and overlap end-to-end, which is characteristic of sigma bonds.
