    Which one of the following is not true for the hydrolysis of t-butyl bromide with aqueous \[NaOH\]?

    A)  Reaction occurs through the \[{{S}_{N}}1\] mechanism

    B)  The intermediate formed is a carbocation

    C)  Rate of the reaction doubles when the concentration of alkali is doubled

    D)  Rate of the reaction doubles when the concentration of t-butyl bromide is doubled

    Correct Answer: C

    Solution :

    Hydrolysis of t-butyl bromide with aqueous \[NaOH\] is an example of \[{{S}_{N}}1\] reaction, therefore rate of the reaction depends only on concentration of halo alkane. Rate \[\propto \] [haloalkane]
