Problem

You may want to reference (Pages 369 - 371) Sections 9.7 and 9.8 while completing this problem.

Consider the H2 ion. Suppose that the ion is excited by light so that an electron moves from a lower-energy to a higher-energy MO. Which of the following statements is correct?
(i) The light excites an electron from a bonding orbital to an antibonding orbital.
(ii) The light excites an electron from an antibonding orbital to a bonding orbital.
(iii) In the excited state there are more bonding electrons than antibonding electrons.
