  1. A 1, 2-Dibromopropane
  2. B 1-Bromopropane
  3. C 2-Bromopropene
  4. D 3-Bromopropene
Verified Solution

Answer & Solution

Correct Answer

(D) 3-Bromopropene

Step-by-step Solution

Detailed explanation

When alkenes are heated with \(\mathrm{Br}_2\) or \(\mathrm{Cl}_2\) at high temperature, hydrogen atom of allylic carbon is substituted with halogen atom giving allyl halide.
\(\mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}_3+\mathrm{Br}_2 \longrightarrow \mathrm{CH}_2=\) \(\mathrm{CH}-\mathrm{CH}_2 \mathrm{Br}+\mathrm{HBr}\)
\( \text { 3-Bromopropene}\)
