Bonding in the Methyl Cation, the Methyl Radical, and the Methyl Anion.

cation radical anion
sp2 hybridization sp2 hybridization sp3 hybridization

The geometry, and hence the hybridization, of these three species depends on the presence or absence of a lone pair. The radical with a single electron is usually pyramidal, like the anion, however, the methyl radical is an exception and is planar as shown in the model.
