In reply to bella. It's easy when there's only one substituent, such as toluene (methylbenzene): C6H5CH3. With two substituents there is the possibility for ortho, meta, para isomers so it requires more than just a condensed formula to describe. e.g. m-C6H4(CH3)2 would be meta-dimethylbenzene (aka m-xylene)

What about writing a condensed formula for a ring? such as a aromatic ring with side chains on it?
