MDCAT Chemistry MCQ #228

  1. Question 1

    Q1. A researcher studying the properties of alcohols observes that the boiling point of butanol is higher than would be expected based on its molecular structure. What is the reason for this increased boiling point?

    • A) Presence of a hydroxyl group
    • B) Length of the carbon chain
    • C) Presence of a hydrogen bond
    • D) Increased van der Waals interactions

    Answer: Presence of a hydrogen bond

    Explanation: The intermolecular hydrogen bonds between butanol molecules increase its boiling point.
