Solution

The correct option is D $C l C H_{2} - C H = C H_{2}$
$C l - C H_{3} - C H = C H_{2}$
$C l + C H_{2} - C H = C H_{2} + N u^{(-)} ⟶ C H_{2} = C H - C H_{2} - N u$
It form Stable carbocation & we also know thta $C l^{(-)}$ is good leaving group.

Which one of the following is most reactive towards nucleophilic substitution reaction?

The correct option is D ClCH2−CH=CH2Cl−CH3−CH=CH2Cl+CH2−CH=CH2+Nu(−)⟶CH2=CH−CH2−NuIt form Stable carbocation & we also know thta Cl(−) is good leaving group.

The correct option is D $C l C H_{2} - C H = C H_{2}$
$C l - C H_{3} - C H = C H_{2}$
$C l + C H_{2} - C H = C H_{2} + N u^{(-)} ⟶ C H_{2} = C H - C H_{2} - N u$
It form Stable carbocation & we also know thta $C l^{(-)}$ is good leaving group.
