The orbital hybridization of the central atom here is sp2.
What is lone pair?
We know that the electrons that are able to occur on the central atom of a compound fall into two categories, the bond pairs and the lone pairs. The bond pairs are the pairs of electrons that are used to combine to other atoms while the lone pairs are the pairs that resides only in the given atom.
In this case, we are told that a central atom has one lone pair and bonds to two other atoms. This implies that we have one lone pair and two bond pairs thus we need about three available orbitals and we find that in sp2 hybridization.
