The number of species below that have two lone pairs of electrons in their central atom is ___ (Round off to the Nearest integer) SF 4 , BF 4 - , ClF 3 , AsF 3 , PCl 5 , BrF 5 , XeF 4 , SF 6

Step-by-step solution

Two l.p. on central atom is = ClF 3 , XeF 4 The valence shell electron pair repulsion (VSEPR) theory is a model used to predict 3-D molecular geometry based on the number of valence shell electron bond pairs among the atoms in a molecule or ion. This model assumes that electron pairs will arrange themselves to minimize repulsion effects from one another.
