MDCAT Chemistry MCQ #599

  1. Question 1

    Q1. A chemist observes that alkyl fluorides are remarkably stable and resistant to substitution compared to other halides. Which factor primarily dictates this lack of reactivity?

    • A) Electronegativity
    • B) Bond energy
    • C) Bond length
    • D) Molecular mass

    Answer: Bond energy

    Explanation: C-F bond energy is the highest among halides, making it extremely difficult to break; electronegativity is tempting but doesn't dictate bond strength.
