WebBromine & Alkenes. Alkenes are a homologous series of hydrocarbon compounds with at least one double bond between two of the carbon atoms on the chain. The double bond can be written as carbon carbon double bond or as C=C. The general formula for alkenes is: CnH2n. Alkenes are generally more desirable than alkanes as they are more reactive due ... WebAs bromine addition to ethene, propene and bromine reaction occurs in same way. First, Br 2 molecule is polarized by alkene bond.
