WebQuestion: A researcher found an old bottle of xylene (a mixture of ortho-dimethylbenzene and meta- dimethylbenzene) in the solvent cabinet. The vapor pressure of pure ortho-dimethylbenzene and pure meta-dimethylbenzene are 650 Pa and 820 Pa receptively. The researcher wants the xylene to have at least 85% purity of meta-dimethylbenzene … WebStudy Notes. You should already know the names and structures of several of the hydrocarbons shown in Figure 15.1. A compound containing a benzene ring which has one or more alkyl substituents is called an arene. A phenyl group consists of a benzene ring with one of its hydrogens removed. Figure 15.1. 1: Two ways of representing a phenyl group.
