The VSEPR theory is predicated on the assumption that the molecule will take a shape that minimises electronic repulsion in the valence shell of that atom. The VSEPR model can predict the structure of nearly any molecule or polyatomic ion with a nonmetal central atom, as well ... 2. The carbon atom forms two double bonds. Each double bond is a group, so there are two electron groups around the central atom. Like BeH 2, the arrangement that minimizes repulsions places the groups 180° apart. 3. Once again, both groups around the central atom are bonding pairs (BP), so CO 2 is designated as AX 2. .
