Question

Complete and balance the following chemical equation:

${\mathrm{C}}_2{\mathrm{H}}_4+{\mathrm{Br}}_2\to \mathrm{\_}$

Answer 1

The chemical reaction involves the reaction of a reactant molecule with a suitable reagent that forms an intermediate which is converted into final products.

The halogenation of alkene is a reaction in which a dihalide is added to a molecule after the double bond linked between Carbon $\left(\mathrm{C}\right)$ atoms has been broken.

The halogen atom is added to the neighboring Carbon atoms from the opposite sides of the molecule.

The bromination reaction of Ethene $\left({\mathrm{C}}_2{\mathrm{H}}_4\right)$ forms the 1,2-dibromoethane as the major product.

The bromination reaction of Ethene can be written as:

$$\begin{gathered} {\mathrm{CH}}_2={\mathrm{CH}}_2+\mathrm{Br}-\mathrm{Br}\to {\mathrm{BrCH}}_2-{\mathrm{CH}}_2\mathrm{Br} \\ \left(\mathrm{Ethene}\right)\left(\mathrm{Bromine}\right)(1,2-\mathrm{dibromoethane}) \end{gathered}$$
