Q. Which of the following is elimination reaction
A) [image:12_image213.emf]
B) $CH_{3}CH_{2}CH_{2}Cl + aq.KOH \longrightarrow CH_{3}CH_{2}CH_{2}OH$
C) $\ ^{\ \ \ \ \ \ \ \ \ \ \ \ \ +}N\left( CH_{3} \right)_{3}$
|
$CH_{3} - C - CH_{2}\ CH_{3}\overset{Alc.KOH\ }{\rightarrow}CH_{3}CH = CHCH_{3}$
|
H
D) $CH_{3} - CH - CH_{2}Br + Alc.KOH\overset{\ \ \mathrm{\Delta}\ \ }{\rightarrow}CH_{3}CH - CH_{2}OH$
| |
$\ \ \ \ \ \ \ \ \ \ \ \ \ Br\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ OH$
Explanation
(c)
$\ ^{+}N\left( CH_{3} \right)_{3}$
|
$CH_{3} - C - CH_{2}CH_{3}\ \overset{Alc.KOH\ }{\rightarrow}CH_{3}CH = CHCH_{3}$
|
$H$
is an example of elimination reaction
