  1. Question 1

    Q1. Which process explains the paramagnetism of an oxygen molecule?

    • A) Presence of paired electrons in p-orbitals
    • B) Unpaired electrons in molecular orbitals
    • C) Alignment of electron spins in an external magnetic field
    • D) Rotation of the molecule in a magnetic field

    Answer: Unpaired electrons in molecular orbitals

    Explanation: Unpaired electrons in O₂'s molecular orbitals cause paramagnetism. Paired electrons result in diamagnetism.
