Description
A methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms — CH3. In formulas, the group is often abbreviated Me. Such hydrocarbon groups occur in many organic compounds. It is a very stable group in most molecules.

The anion has eight valence electrons, the radical seven and the cation six. All three forms are highly reactive and rarely observed,
