  1. Question 1

    Q1. According to Molecular Orbital Theory, the bond order of the O2+ ion is calculated using its electron configuration. What is the resulting bond order?

    • A) 1.5
    • B) 2.0
    • C) 2.5
    • D) 3.0

    Answer: 2.5

    Explanation: O2+ has 10 bonding and 5 antibonding electrons; (10-5)/2 = 2.5. 2.0 is the bond order for neutral O2, which has 6 antibonding electrons.
