What type of reaction takes place when a halogen reacts with ethene? Give the complete chemical equation for this reaction

When a halogen reacts with ethene, it undergoes a halogenation reaction. In this reaction, the halogen replaces one of the hydrogen atoms in ethene, resulting in the formation of a halogenated hydrocarbon.

The complete chemical equation for the reaction between a halogen (X2) and ethene (C2H4) can be represented as follows:

C2H4 + X2 → C2H4X2

Here, X represents the halogen atom, such as chlorine (Cl2), bromine (Br2), or iodine (I2). The reaction results in the formation of a halogenated hydrocarbon, where the halogen atom is attached to one of the carbon atoms in the ethene molecule.
