  1. Question 1

    Q1. The hydrolysis of 2-bromo-2-methylpropane follows a mechanism where the rate is independent of the hydroxide ion concentration. How is this molecularity classified?

    • A) Unimolecular
    • B) Bimolecular
    • C) Termolecular
    • D) Zero order

    Answer: Unimolecular

    Explanation: SN1 is unimolecular because the rate-determining step only involves the alkyl halide; bimolecular is wrong as it describes the SN2 mechanism.
