Alkylbenzenes
The alkylbenzenes are derivatives of benzene , in which one or more hydrogen atoms are only exchanged for alkyl groups of different sizes. They are a subgroup of the aromatic hydrocarbons . The simplest representative is toluene , in which one hydrogen atom in benzene has been replaced by a methyl group .

Depending on the type, number and properties of the substituents, further subgroups can be formed.
- The most common and well-known aromatic hydrocarbons B Enzol, T oluol, E thylbenzol and X ylol be handled with the group of BTEX aromatics together.
- The methyl-substituted benzenes are derived from benzene, in which one or more hydrogen atoms are replaced by a methyl group.
- As C 2 -benzenes , C 3 -benzenes , C 4 -benzenes , etc. respectively refers to a group of compounds in which benzene is substituted with a respective fixed number of other carbon atoms only in the form of alkyl radicals.
The alkylbenzene category provides an overview .
