Answer : Option B) By breaking a carbon double bond and adding chlorine.

Explanation : When chlorine reacts with ethene it forms dicholoroethane. It reacts spontaneously to form product. The halogenation reaction takes place in ethene across the double bonds and removes the hydrogen from ethene and two chlorine atoms gets attached in their place; which results in dichloroethane as the product.

Answer: option B m

Explanation:

It is an example for Electrophilic Addition of Halogen. And addition of Cl2 to Alkene is always Trans Addition. That means both cl atoms should add opposite side of double bond and results vicinal 1,2-dichloroethane as a product.

CH2=CH2 + Cl2-------> ClCH2CH2Cl
