BF3 Hybridization
Boron trifluoride (BF3) is a colorless, odorless gas that is used in a variety of industrial applications, including the production of polymers, plastics, and semiconductors. The hybridization of the BF3 molecule is sp2, which means that the boron atom has three sp2 hybrid orbitals and one unhybridized p orbital.
The sp2 hybrid orbitals are formed by the mixing of the boron atom’s 2s orbital and two of its 2p orbitals. This mixing of orbitals results in three new orbitals that are arranged in a trigonal planar configuration. The unhybridized p orbital is perpendicular to the plane of the sp2 hybrid orbitals.
The three sp2 hybrid orbitals of the boron atom overlap with the 2p orbitals of the three fluorine atoms to form three sigma bonds. The bond angle between any two fluorine atoms is 120 degrees.
The unhybridized p orbital of the boron atom contains a lone pair of electrons. This lone pair of electrons can participate in pi bonding with other atoms, but it does not participate in the bonding in BF3.

Additional Information
The hybridization of the BF3 molecule can be determined using the following steps:
- Write the Lewis structure of the BF3 molecule.
- Count the number of valence electrons on the boron atom.
- Determine the number of hybrid orbitals needed to accommodate the valence electrons on the boron atom.
- Assign the correct hybridization to the boron atom based on the number of hybrid orbitals needed.
In the case of BF3, the Lewis structure shows that the boron atom has three valence electrons. Three hybrid orbitals are needed to accommodate these three valence electrons. Therefore, the hybridization of the boron atom in BF3 is sp2.
