Question

What happens when ethene combines with hydrogen chloride.

Answer 1

In an organic reaction, the reagent reacts with a reactant molecule to produce an intermediate which is converted into final products.

A chemical reaction in which two or more reactants react together to form a single larger product is called an addition reaction.

The reaction of Ethene $\left({\mathrm{C}}_2{\mathrm{H}}_4\right)$ and Hydrogen chloride $\left(\mathrm{HCl}\right)$ forms Chloroethane $\left({\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{Cl}\right)$ as the major product. This reaction is an addition reaction.

The reaction of Ethene and Hydrogen chloride is written as:

$$\begin{gathered} {\mathrm{CH}}_2={\mathrm{CH}}_2+\mathrm{H}-\mathrm{Cl}\to {\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{Cl} \\ \left(\mathrm{ethene}\right)(\mathrm{hydrogen}(\mathrm{chloroethane}) \\ \mathrm{chloride}) \end{gathered}$$
