MCQ
Deviation from Markownikoff's rule occurs in presence of
- AZinc
- ✓Peroxides
- C$Hg - Zn/HCl$
- DAll of these
✓
Answer
Correct option: B.
Peroxides
b
(b) $C{H_3} - CH = C{H_2} + HBr \xrightarrow{Markownikoff\,rule} \mathop {C{H_3} - \mathop {CH}\limits_{\mathop {|\,\,\,\,\,\,}\limits_{Br\,\,} } - C{H_3}}\limits_{2 - {\rm{Bromopropane}}} + HBr$
(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 }}} $
