    Q1. The order of reactivity of alkyl halides towards SN2 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, so methyl > primary > secondary > tertiary.
