Question

​Write a balanced chemical equation for each of the known hydrocarbons that reacted with bromine solution

Answer 1

Dear Student,
Alkenes are the class of hydrocarbons that react with bromine solution and decolourize it.This serves as a test for unsaturation of alkenes.
The general reaction would be
$RC{H}_2=C{H}_{2}R+B{r}_2\to R-C{H}_{2}Br-C{H}_{2}Br-R$
