Solution

The correct option is D $C H_{3} - C H_{2} - C | B r H - C H_{3}$
Dehydrohalogenation is an organic reaction in which the alkyl halide halide on reaction with alcoholic KOH ,gives the corresponding alkene. Thus 2-butene can be obtained as:
$C H_{3} - C H_{2} - C H (B r) - C H_{3} + K O H \to C H_{3} - C H = C H - C H_{3} + K C l + H_{2} O$
