MDCAT Chemistry MCQ #1735

  1. Question 1

    Q1. Water has a significantly higher boiling point (100 C) compared to Hydrogen sulfide (-60 C). This is primarily due to:

    • A) Greater molar mass of water
    • B) Extensive intermolecular hydrogen bonding
    • C) Stronger London dispersion forces
    • D) Higher electronegativity of Sulfur

    Answer: Extensive intermolecular hydrogen bonding

    Explanation: Intermolecular hydrogen bonding increases the energy needed for boiling. Option D fails because Oxygen is more electronegative than Sulfur, not less.
