Question

CH2=CH2+Br2–CH2-CH2?

Answer 1

CH2=CH2 + Br2 —> CH2Br-CH2Br

Answer 2

The chemical equation you've provided seems to be a reaction between ethene (CH2=CH2) and bromine (Br2) to form 1,2-dibromoethane (CH2Br-CH2Br). This reaction is a type of addition reaction, where the bromine molecule adds across the carbon-carbon double bond in ethene.

The balanced chemical equation for this reaction is as follows:

CH2=CH2 + Br2 → CH2Br-CH2Br

In this reaction, each bromine atom adds to one of the carbon atoms in the double bond of ethene, resulting in the formation of 1,2-dibromoethane (also known as ethylene dibromide).

It's worth noting that this reaction requires the presence of a suitable solvent or catalyst, such as a halogen carrier like iron or aluminum halides, to facilitate the reaction.
