A dilute solution of bromine is added to samples of heptane and cyclohexene. The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, ...

2H2O Br–(aq) + HOBr(aq) + H+(aq) → Br2(aq) + H2O(l) However, other detailed studies of the processes occurring give a variety of colorless bromate ions and bromic acid molecules as intermediates, ...
