  • C
    $Hg - Zn/HCl$
  • D
    All of these
✓

Answer

Correct option: B.
Peroxides
b
(b) $C{H_3} - CH = C{H_2} + HBr \xrightarrow{Markownikoff\,rule} \mathop {C{H_3} - \mathop {CH}\limits_{\mathop {|\,\,\,\,\,\,}\limits_{Br\,\,} }  - C{H_3}}\limits_{2 - {\rm{Bromopropane}}}  + HBr$

$\xrightarrow{presence \,of\, peroxide} \mathop {C{H_3} - C{H_2} - C{H_2} - Br}\limits_{{\rm{1 - Bromopropane  }}} $
