The H–N–H bond angles in NH3 are slightly smaller than the 109.5° angle in a regular tetrahedron (Figure \(\PageIndex{6}\)) because the lone pair-bonding pair repulsion is greater than the bonding pair-bonding pair repulsion. In this article, you will get the entire information regarding the molecular geometry of NH3 like its Lewis structure, electron geometry, hybridization, bond angles, and molecular shape. The P1-N1 and N2-C2 bond lengths of 1.810 Å and 1.475 Å , respectively, and the P1-N1-P2 angle of 136.3°were obtained using the PM3 method, while as shown in Table 3, the actual values of these parameters are 1.694(3) Å , 1.446(5) Å and 128.54°, respectively.

Hybridization theory lacks intuitive simplicity of VSEPR theory. Multiple bonds are combinations of one sigma bond and one or two pi bonds. After you have considered the information in the table, you may want to review the summary of bonding options in Table 3 of our discussion of Lewis structures. The O-Na bond, because the electrons are shared unevenly and located on oxygen, so it will be the source of the reaction for a new bond. Since head-to-head overlap localizes the electron pair in the internuclear region more than side-to-side overlap does, the electrons in a sigma bond experience greater nuclear attraction than the electrons in a pi bond.
