  1. Question 1

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

    • A) CH₃ > 1° > 2° > 3°
    • B) 3° > 2° > 1° > CH₃
    • C) 1° > 2° > 3° > CH₃
    • D) 2° > 1° > CH₃ > 3°

    Answer: CH₃ > 1° > 2° > 3°

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