Q. Which of the following requires radical intermediate?
A) $CH_{3} - \ CH = CH_{2} + HBr \longrightarrow {CH}_{3} - CH - {CH}_{3}\$
|
$Br$
B) [image:12_image165.emf]
C) $CH_{3} - CH = CH_{2} + HBr \rightarrow CH_{3} - {CH}_{2} - CH_{2} - Br$
D) $CH_{3}CHO + NH_{2}OH\overset{{\ \ \ \ \ \ \ \ \ \ H}^{+}\ \ \ \ \ \ }{\rightarrow}\ {CH}_{3} - CH = N - OH$
Explanation
(c)
$CH_{3} - CH = CH_{2} + HBr\underset{\ \ peroxide\ \ }{\overset{\ \ \ Organic\ \ \ \ \ }{\rightarrow}}CH_{3} - CH_{2} - CH_{2} - Br$
requires radical intermediate.
