Each can bond with a 2 p orbital from a fluorine atom to form the trigonal planar BF 3 molecule. Figure 9.23. 7: The process of s p 2 hybridization is the mixing of an s orbital with a set of two p orbitals ( p x and p y) to form a set of three s p 2 hybrid orbitals. Each large lobe of the hybrid orbital points to one corner of a planar triangle.
