Verified Solution

Answer & Solution

Correct Answer

(D) 3-Chloropropene

Step-by-step Solution

Detailed explanation

When an alkene is heated with \(\mathrm{Cl}_2\) at high temperature, hydrogen atom of allylic carbon is substituted with halogen atom giving allyl halide.
\(\mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}_3+\mathrm{Cl}_2 \longrightarrow\)
\(\mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}_2 \mathrm{Cl}+\mathrm{HCl}\text { 3 - Chloropropene}\)
