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.
