The rate of reaction of $t$-butyl bromide and . $\mathrm{NaOH}$ in water depends on the concentration of
  1. both $t$-butyl bromide and $\mathrm{NaOH}$
  2. $\mathrm{NaOH}$
  3. independent of concentration
  4. $t$-butyl bromide

Solution

Hydrolysis of $t$-butyl bromide with aqueous $\mathrm{NaOH}$ is an example of $\mathrm{S}_{\mathrm{N}} 1$ reaction. The formation of carbocation is the slow step and therefore rate determining step. The rate of the reaction depends only on concentration of tertiary butyl bromide. . Step I. Formation of carbocation
Step 2. Attack of nucleophile on carbocation
