  • VSEPR Theory P.2: How To Draw Molecules; Polarity Considerations The basic rules for drawing molecules as indicated by VSEPR theory always begins with a correctly drawn Lewis structure. The steric number includes both lone pairs and bonding pairs on the central atom. The resulting geometry is always decided by the steric number, but the shape of the molecule as perceived by experimental measurement only "sees" bonding pairs. The names of molecular geometry are assigned on the basis of the bonding pairs. For example, iodine trichloride possesses two lone pairs and three bonding pairs. The geometry of the molecule is shaped like a trigonal bipyramid, but it is referred to as T-shaped because the lone pairs are essentially invisible to the measuring techniques used to determine molecular geometry. The example of iodine trichloride is also used to compare which of three possible geometries results in the least number of unfavourable repulsions between electron pairs. The three possible configurations have two, one and no lone pairs in the equatorial postion which serves to illustrate how a 120° bond angle remedies the unfavourable repulsions that occur between electron pairs at 90°. The most stable configuration of iodine trichloride has a minimum number of lone pair bonding pair interations and no lone pair lone pair interactions.
