Q.
The reaction: $\left(\left(CH\right)_{3}\right)_{3}C-Br\overset{H_{2} O}{ \rightarrow }\left(\left(CH\right)_{3}\right)_{3}C-OH$ is a/an
NTA AbhyasNTA Abhyas 2022
Solution:
In this reaction, first of all, the formation of a carbocation occurs by the removal of bromide ion. Then, $H_{2}O$ molecule attacks the carbocation, and an intermediate (protonated alcohol) is formed. This oxonium ion undergoes deprotonation with the help of a water molecule to give rise to an alcohol and a hydronium ion.
This is an example of a nucleophilic substitution reaction. As the substitution occurs by forming a tertiary carbocation, it is a type of unimolecular nucleophilic substitution reaction $\left(\right.S_{N}1\left.\right)$ .
