Question

Tertiary butyl halide on boiling with water gives tertiary butyl alcohol . The reaction follows

• A. $SE$ mechanism
• B. $S_{N}1$ mechanism
• C. $S_{N}2$ mechanism
• D. $E1$ mechanism

Answer 1

The correct option is B $S_{N}1$ mechanism

Teritary butyl halide on boiling with water gives teritary butyl alcohol. The reaction following $S_{N}1$ mechanism.


The slow step is the formation of a carbocation. As this step includes one reactant, then the reaction takes place via $S_{N}1$ mechanism.
