“Xylyl” refers to a chemical group or radical composed of three methyl (CH3) groups attached to a benzene ring. It is often used in the context of organic chemistry to describe certain compounds that contain this specific arrangement of atoms.
The term “xylyl” is derived from the name of the compound “xylene,” which is a type of aromatic hydrocarbon containing two methyl groups attached to a benzene ring. The “-yl” suffix is commonly used in organic chemistry to indicate a substituent or radical.
- 1,2,3-Trimethylbenzene radical
- Monomethylbenzene (single methyl group on a benzene ring)
- Di-methylbenzene (two methyl groups on a benzene ring)
A unique example of a compound containing the xylyl group is “1,2,3-trimethylbenzene,” also known as mesitylene. This compound consists of three methyl groups attached to a benzene ring in a specific arrangement, representing the xylyl group.
