  1. Question 1

    Q1. In a synthesis lab, a chemist treats 2-bromopropane with alcoholic KOH at a high temperature. What is the major organic product formed?

    • A) n-Propane
    • B) 2-Propanol
    • C) Propene
    • D) 1-Propanol

    Answer: Propene

    Explanation: Alcoholic KOH promotes elimination (E2) to form alkenes. Aqueous KOH is tempting but it would favor substitution to form propanol.
