Question

Write the reaction of ethene with bromine.

Answer 1

The organic compounds containing Carbon $\left(\mathrm{C}\right)$ atoms and having double bonds between two Carbon atoms are called unsaturated hydrocarbons.

The halogenation of alkene is a reaction in which a dihalide is added to a molecule after the double bond linked between Carbon atoms has been broken.

The Halogen atoms add to the neighboring Carbon atoms from the opposite sides of the molecule to give the halogenated product.

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

The reaction of Ethene with Bromine $\left(\mathrm{Br}\right)$ molecule can be written as:

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