  1. Question 1

    Q1. The decreasing order of reactivity of alkyl halides towards E2 is?

    • A) 3° > 2° > 1°
    • B) 1° > 2° > 3°
    • C) 2° > 1° > 3°
    • D) 1° > 3° > 2°

    Answer: 3° > 2° > 1°

    Explanation: The reactivity towards E2 elimination increases with the stability of the alkene formed, hence 3° > 2° > 1°.
