  1. Question 1

    Q1. In the elimination reaction of an alkyl halide following the E2 mechanism, the overall order of the reaction is:

    • A) First order
    • B) Zero order
    • C) Second order
    • D) Third order

    Answer: Second order

    Explanation: Rate = k[RX][Base] defines the second-order kinetics of E2; SN1/E1 are first-order, depending only on the substrate concentration.
