Bromine water + ethene
WebApr 9, 2016 · Because ethene is an alkene, which is a less stable structure than an alkane. Bromine opens the double bond in ethene, rather than replacing hydrogen. This gives ethene an alkane structure. Explanation: Ethene and bromine are an addition reaction because ethene is an alkene - it has a double bond.
