  1. Question 1

    Q1. When comparing the boiling points of Ethanal (MW 44) and Propane (MW 44), which statement correctly describes the trend observed in PTB?

    • A) Higher than Alcohols
    • B) Lower than Alkanes
    • C) Higher than Alkanes
    • D) Equal to Ethers

    Answer: Higher than Alkanes

    Explanation: Aldehydes have higher boiling points than alkanes due to dipole-dipole forces, but lower than alcohols because they lack intermolecular hydrogen bonding.
