Question

Which of the following molecular orbitals possess minimum energy?
(A) σ2pz
(B) σ1s
(C) σ2s*
(D) π2pₓ

Answer 1

Molecular orbitals possess minimum energy of σ1s.

Therefore, Option B is the correct answer.

Explanation:

Because electrons in the σ1s orbital interact simultaneously with both nuclei, they have a lower energy than electrons that interact with only one nucleus.

This means that the σ1s molecular orbital has a lower energy than either of the hydrogen 1s atomic orbitals.
