The valence electrons on the central atom in both NH 3 and H 2 O should be distributed toward the corners of a tetrahedron, as shown in the figure below. Q. VSEPR theory uses the fact that electron pair repulsions go, lone pair/lone pair>lone pair/bond pair>bond pair/bond pair so you would expect the smallest angle to be HOH in water. So what happens when we have a lone pair is that it pushes down on the bond. a. CH 4 b. H 2 O c. BH 3 d. PH 3 e. SF 6. So we know that lone pairs have a a year, uh, or take up more space. So the electron, a geometry for water is Tetra hydro, which gives a bond angle of 109.5.
