  1. Question 1

    Q1. Among the following isomers of C4H9Br, which one is expected to have the lowest boiling point due to its molecular shape?

    • A) n-Butyl bromide
    • B) Isobutyl bromide
    • C) sec-Butyl bromide
    • D) tert-Butyl bromide

    Answer: tert-Butyl bromide

    Explanation: Branching decreases the surface area and van der Waals forces, lowering the boiling point; n-butyl bromide has the highest surface area.
