MDCAT Chemistry MCQ #1738

  1. Question 1

    Q1. While electronegativity usually tracks with electron affinity, Chlorine has a higher electron affinity than Fluorine. This exception exists because:

    • A) Fluorine has a higher nuclear charge
    • B) Chlorine has less inter-electronic repulsion
    • C) Fluorine's 2p subshell is very large
    • D) Chlorine is more electronegative than Fluorine

    Answer: Chlorine has less inter-electronic repulsion

    Explanation: Chlorine's larger size reduces electron-electron repulsion compared to Fluorine. Option D fails because Fluorine is actually more electronegative than Chlorine.
