The steric number is the number of atoms bonded to a central atom of a molecule plus the number of lone pairs attached to the central atom. To determine the steric number, you use the Lewis structure. The presence of lone pairs has a distorting effect on the bond angles, as illustrated by the examples below. Central carbon atom forms two bonds with both Hydrogen and Chlorine atoms. STEP-5: Assign hybridization and shape of molecule . Summing up the number of σ-bond formed by the desired atom (here I) and the number of lone pair on it we can easily know the hybridization of it. Continuing in the same way, a steric number of 4 leads to tetrahedral structure, 5 gives a trigonal bipyramidal structure and a steric number of 6 leads to an octahedral structure. It is slightly toxic to humans, on account of its tendency to react in the human body and produce reactive species of nitrogen and oxygen, which can damage internal structures. As the steric number is 5, the hybridization of is inferred as . A simple example of steric activity is that of SnCl2 which is bent in accordance with VSEPR theory.
