Q. 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.
Explanation
(c)
The reaction between $tert$-butyl bromide and hydroxide ion yields $tert$-butyl alcohol and follows the first order kinetics. The rate of reaction depends upon the concentration of only one reactant, which is tertiary butyl bromide.
