In the following sequence of reaction,

${CH}_{3} {CH}_{2} {CH}_{2} {CH}_{2} Br \overset{alc. KOH}{\to} A \overset{HBr}{\to} B \overset{aq. KOH}{\to} C$ ,

The product 'C' is ?

Options:

Answer:

Solution:

$\begin{matrix} C H_{3} C H_{2} C H_{2} C H_{2} B r & \overset{a l c . K O H}{\to} & C H_{3} - C H_{2} - C H = C H_{2} + H B r \overset{H B r}{\to} & C H_{3} C H_{2} \underset{\overset{|}{B r}}{C H} - C H_{3} & \overset{aq . KOH}{\to} & C H_{3} - C H_{2} - \underset{\overset{|}{OH}}{C H} - C H_{3} \\ (A) & (B) & (C) \end{matrix}$
