But now we have bromine, we have two BRS, we have a halogen. And that means we have to refer to rule number one, which states replace halogens with hydrogens. So since we have two halogens, that means we have two more H atoms. So we have eight plus two, a total of ten H atoms. So our x is ten. So two times five plus two, that's twelve minus ten, that's two divided by two gives us or two divided by two gives us one.
