  1. Question 1

    Q1. What accounts for the paramagnetism of oxygen molecules?

    • A) Unpaired electrons in π* molecular orbitals
    • B) Fully filled molecular orbitals
    • C) Diamagnetic core electrons
    • D) Zero bond order

    Answer: Unpaired electrons in π* molecular orbitals

    Explanation: O₂'s molecular orbital configuration has two unpaired electrons in π* orbitals, causing paramagnetism.
