  1. Question 1

    Q1. A researcher studying the properties of alcohols observes that ethanol has a higher boiling point than methanol. What structural feature of ethanol contributes to this higher boiling point?

    • A) Presence of a hydroxyl group
    • B) Length of the carbon chain
    • C) Presence of a methyl group
    • D) Presence of a hydrogen bond

    Answer: Presence of a hydrogen bond

    Explanation: The intermolecular hydrogen bonds between ethanol molecules increase its boiling point, while methanol lacks this feature.
