Q. According to Markownikoff’s rule, what will be the major product of reaction $CH_{2} = CH - CH_{3}\overset{HBr\ \ \ }{\rightarrow}$ ?
A) $Br$
|
$CH_{3} - CH - CH_{3}$
B) $Br - CH_{2} - CH_{2} - CH_{3}$
C) $CH_{2} = CH - CH_{2}Br$
D) $CH_{2} = C = CH_{2}$
Explanation
(a)
According to Markownikoff’s rule, the negative part of the reagent gets attached to that double bonded carbon atom which has least number of H-atoms. Thus,
$CH_{3} = CH - CH_{3}\overset{HBr}{\rightarrow}CH_{3} - CH - CH_{3}$

$Br$
