Benzyl features a benzene ring attached to a CH group.

All groups of carbonaceous chondrites except the CH group are named for a characteristic type specimen:

In studying organic compounds, Kopp found a regular relationship between boiling points and the number of CH groups present.

It is related to tetrahydrofuran by interchange of one oxygen for a CH group.

This can be extended to any CH group.

A CH group connected to two vinyl groups is said to be doubly allylic.

The CH group allows it to be covalently linked to surrounding biomolecules during aldehyde fixation.

Acridine is structurally related to anthracene with one of the central CH groups is replaced by nitrogen.

These compounds are related to the corresponding quinones by replacement of the oxygen atoms by CH groups.

The term methylation in organic chemistry refers to the alkylation process used to describe the delivery of a CH group.
