Final answer:
The structural formula for the products formed from the reaction of Cl2 and C2H4 is 1,2-dichloroethane, which is represented as Cl-CH2-CH2-Cl.
Step-by-step explanation:
The student is asking what the structural formula of the products formed from the reaction between chlorine (Cl2) and ethene (C2H4) would be. The product of this reaction is 1,2-dichloroethane, which has the structural formula Cl-CH2-CH2-Cl.
When ethene reacts with chlorine, a halogenation reaction occurs, where the double bond in ethene opens up, and each carbon atom bonds with a chlorine atom. This can be represented by the equation: C2H4 + Cl2 → Cl-CH2-CH2-Cl. This product is often used in various industrial applications, including as a solvent and precursor for the production of other chemicals.
