In which of the organic reaction alcoholic solution of $K O H$ is used?

Options:

Answer:

Solution:

$C H_{3} C H_{2} B r + a l c K O H \overset{D e h y d r o h a l o g e n a t i o n}{\to}$ $C H_{2} = C H_{2} + K B r + H_{2} O$
In alcoholic $K O H,$ hydroxide ions $(O H^{-})$ are present which is a strong base. They abstract a proton from beta carbon of alkyl halide and favours elimination reaction.
