MDCAT Chemistry MCQ #851

  1. Question 1

    Q1. Why is the electron affinity of fluorine lower than that of chlorine?

    • A) Smaller atomic radius of fluorine
    • B) Stronger nuclear charge in fluorine
    • C) Electron-electron repulsion in smaller fluorine
    • D) Higher ionization energy of fluorine

    Answer: Electron-electron repulsion in smaller fluorine

    Explanation: Fluorine's smaller size causes repulsion in added electrons, reducing electron affinity compared to chlorine.
