Question

What happens when (give balanced chemical equation and write the names of the reactants and products in each case):

Ethyne reacts with chlorine in the sunlight

Answer 1

Step 1:

Ethyne $\left({\mathrm{C}}_2{\mathrm{H}}_2\right)$ gives different types of oxidation reaction which depends on experimental conditions like temperature, pressure, catalyst, and presence and absence of light.

Ethyne gives addition reaction with Hydrogen $\left({\mathrm{H}}_2\right)$ and Halogens

Step 2: Reaction

The chemical reaction of Ethyne with Chlorine $\left({\mathrm{Cl}}_2\right)$ in the presence of light.

$$\begin{gathered} \mathrm{H}-\mathrm{C}\equiv \mathrm{C}-\mathrm{H}+{\mathrm{Cl}}_2\to 2\mathrm{C}+2\mathrm{HCl} \\ \mathrm{Ethyne}\mathrm{Chlorine}\mathrm{Carbon}\mathrm{Hydrochloric}\mathrm{acid} \end{gathered}$$
