Q.
$CH _{3}- CH = CH _{2}+ HOBr \longrightarrow P$; The major product ' $P$ ' is
Haloalkanes and Haloarenes
Solution:
HOBr Breaks as
$HO - Br \longrightarrow \underset{\left( Nu ^{-}\right)}{ H O^-} + \underset{\left( E ^{+}\right)}{ Br ^{+}}$
And alkene follows electrolphylic addition reaction. So, $Br ^{+}$attack at first and then $OH$ attack.
