# What is the product of ethene mixed with bromine?

Apr 30, 2016

In an inert solvent $\text{1,2-dibromoethane}$ is the likely product.

#### Explanation:

Ethylene is an electron-rich nucleophile, and bromine is a potential electrophile.

${H}_{2} C = C {H}_{2} +$ ""^(delta+)Br-Br^(delta-) $\rightarrow {H}_{2}^{+} C - C {H}_{2} - B r + B {r}^{-}$ $\rightarrow B r {H}_{2} C - C {H}_{2} B r$

After the first addition, of course the intermediate is on the lookout for a nucleophile; bromide ion can fit the bill.
