MCQ
Ethylene reacts with bromine to form
- AChloroethane
- ✓Ethylene dibromide
- CCyclohexane
- D$1-$ bromo propane
✓
Answer
Correct option: B.
Ethylene dibromide
b
(b) When ethylene reacts with bromine, it forms ethylene dibromide.
(b) When ethylene reacts with bromine, it forms ethylene dibromide.
$\mathop {{H_2}C = C{H_2}}\limits_{{\text{Ethylene}}} \; + \mathop {B{r_2}}\limits_{{\text{Bromine}}} \to $ $\mathop {\begin{array}{*{20}{c}}
