  1. Question 1

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

    • A) CH₃X > C₂H₅X > C₃H₇X
    • B) C₃H₇X > C₂H₅X > CH₃X
    • C) C₂H₅X > CH₃X > C₃H₇X
    • D) C₃H₇X > CH₃X > C₂H₅X

    Answer: CH₃X > C₂H₅X > C₃H₇X

    Explanation: SN2 reactivity decreases with increasing alkyl group size due to steric hindrance.
