Identify the hybrid orbitals used by the atom in boldface red type in each of the following species: (a) BF3; (b) AsF3; (c) BrF3; (d) SeF31.

When figuring out hybrid orbitals, first identify the number of electron densities surrounding the atom in question. In (a), BF3 is characterized by B bonded to three F atoms in single bonds. According to the chart, the three bonds (electron densities) would allow the B in BF3 to use a s1p2 (sp2) hybrid orbital.
1 --> s1
2 --> s1p1
3 --> s1p2
4 --> s1p3
5 --> d1s1p3
