    Q1. What is the order of reactivity of alkyl halides towards SN2 reaction?

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

    Answer: CH3X > 1° > 2° > 3°

    Explanation: SN2 reactivity decreases with increasing steric hindrance, so the order is methyl > primary > secondary > tertiary.
