WebMay 26, 2024 · Xylene is an organic compound having the chemical formula (CH 3) 2 C 6 H 4. It falls under the category of dimethylbenzene because it has a benzene with two attached methyl groups. Furthermore, this … WebIn this report, the terms xylene, xylenes, and total xylenes will be used interchangeably. There are three forms of xylene in which the methyl groups vary on the benzene ring: meta-xylene, ortho-xylene, and para-xylene (m-, o-, and p-xylene). These different forms are referred to as isomers. The term total xylenes refers to all three isomers of xylene (m-, o-, and p-xylene).
