Question

What is the condensed structural formula for toluene with bromine?

Answer 1

Not sure what you mean by "with bromine", as you could mean bromine is on the methyl group, or on the ring directly. Either way, the condensed structural formula is:

• `"C"_6"H"_5"CH"_2"Br"` - if bromine is on the methyl group

• `"C"_6"H"_4"CH"_3"Br"` - if bromine is directly on the ring; note that this is the ortho isomer, and the meta and para isomers exist as well.

Their molecular formulas are identical (`"C"_7"H"_7"Br"`), so it wouldn't be productive to use that in this case.
