Answer Details
When excess chlorine is mixed with ethene at room temperature, the product is 1,2-dichloroethane.
The reaction between ethene and excess chlorine is an example of an addition reaction. In this reaction, the double bond in ethene is broken, and chlorine atoms add to the carbon atoms to form a new molecule. The product formed in this reaction depends on the conditions under which the reaction occurs.
When excess chlorine is mixed with ethene at room temperature, the reaction proceeds in a stepwise manner to form 1,2-dichloroethane as the major product. The first chlorine atom adds to one of the carbon atoms in ethene, and the second chlorine atom adds to the adjacent carbon atom, forming a molecule with two chlorine atoms attached to adjacent carbon atoms, which is 1,2-dichloroethane.
Therefore, the product formed when excess chlorine is mixed with ethene at room temperature is 1,2-dichloroethane.
