Q. Amongst the following, HBr reacts fastest with
A) Propane-1-ol
B) Propane-2-ol
C) 2-methyl propane-1-ol
D) 2-methyl propane-2-ol
Explanation
(d)
$ROH + HBr \rightarrow R - Br + H_{2}O$
The rate of reaction is fastest for $3{^\circ}$ alcohol.
The rate of reaction decreases as fallows
$3{^\circ} > 2{^\circ} > 1{^\circ}$
