  1. Question 1

    Q1. The reactivity order of alkyl halides towards SN2 reaction is

    • A) CH3X > 1° > 2° > 3°
    • B) 3° > 2° > 1° > CH3X
    • C) 1° > 2° > 3° > CH3X
    • D) 2° > 1° > CH3X > 3°

    Answer: CH3X > 1° > 2° > 3°

    Explanation: SN2 reactivity decreases with increasing steric hindrance, hence order is CH3X > 1° > 2° > 3°.
