We know that
BF3 has a boron atom with three outer-shell electrons in its ground state and three fluorine atoms containing seven outer electrons. If we observe further closely, one boron electron is unpaired in the ground state. During the formation, 2s orbital and two 2p orbitals hybridize. One of the empty p-orbital is left behind as the lone pair.
- The number of electrons around the boron atom is 6.
- sp2 is the hybridization of B
- It is of trigonal planar shape.
