It would be tetrahedral, with something like C2v symmetry. The electron pair geometry around N is tetrahedral, but there is one lone pair, making the molecular geometry trigonal pyramidal.. 1 0. Still have questions? 1 1. Viewing Notes: In the H 3 PO 4 Lewis structure Phosphorous (P) is least electron electronegative atom and goes in the center of the Lewis structure. For H3PO3, this leaves us with an excess 2 H and one O with one lone pair on phosphorous. The N atom is tetrahedral with one apex occupied by the lone pair so trigonal pyramid just like NH3. Produces irritating vapor. Phosphorous acid is the compound described by the formula H 3 PO 3.This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula.
