Answer: A normal tetrahedron has four points that are 109.5° apart, and the hybridization of one’s orbital with three p orbitals results in four hybrid orbitals that are orientated in that direction. Planar CH3 (methyl free radical) possesses a sp2 hybridization of the C atom, resulting in its planar structure.
A 2pz orbital with an unhybridized electron is present
In addition, (methyl carbonium ion) is also planar (sp2).
The lone pair of electrons is located in one of the hybrid orbitals of the (methyl carbanion) tetrahedral structure (sp3).
The carbanion has three paired bonds and one lone pair. There are four sides to a tetrahedral planter, according to VSEPR theory.
