Question: Major product of the following reaction is \[CH_{3}\underset{H}{\underset{|}{\overset{Br}{\overset{...

Major product of the following reaction is

CH3−C−∣Br∣HCH2−CH3+alco.KOH→CH_{3}\underset{H}{\underset{|}{\overset{Br}{\overset{|}{- C -}}}}CH_{2} - CH_{3} + alco.KOH \rightarrow

A

Butene-1

B

Butene-2

C

Butane

D

Butyne-1

Answer

Butene-2

Explanation

Solution

CH3−CH∣Br−CH2−CH3+KOH(alc)→CH_{3} - \overset{\overset{Br}{|}}{CH} - CH_{2} - CH_{3} + \underset{\left( \text{alc} \right)}{KOH} \rightarrow

CH3−CH=CH−CH3Butene-2+KBr+H2O\underset{\text{Butene-2}}{CH_{3} - CH = CH - CH_{3}} + KBr + H_{2}O
