  1. Question 1

    Q1. A student compares the boiling points of four organic compounds with similar molecular masses. Which compound exhibits a higher boiling point than n-butane but lower than propan-1-ol?

    • A) n-Butane
    • B) Diethyl ether
    • C) Propan-1-ol
    • D) Ethanal

    Answer: Ethanal

    Explanation: Aldehydes have higher boiling points than alkanes due to dipole-dipole forces, but lower than alcohols which possess strong intermolecular hydrogen bonding.
