Tetramethylbenzene

The tetramethylbenzenes constitute a group of substances of aromatic hydrocarbons, which structure consists of a benzene ring with four methyl groups (–CH₃) as a substituent.^[1] Through their different arrangement, they form three structural isomers with the molecular formula C₁₀H₁₄. They also belong to the group of C₄-benzenes. The best-known isomer is durene.^[2]
