Step 1
Which classification(s) applies to the reaction between ethene and chlorine?
Answer
The reaction between ethene and chlorine is classified as a substitution reaction. In this process, a chlorine molecule replaces one of the hydrogen atoms in ethene, leading to the formation of 1,2-dichloroethane. Additionally, this reaction involves an addition of Cl₂ to the double bond of ethene, making it an addition reaction as well.
Thus, the correct classifications are 1 (addition) and 2 (substitution). The answer to the question is option A: 1 and 2.
