WebApr 24, 2024 · The irreducible representations of a point group are labeled according to their symmetry species as follows: 1D representations are labeled A or B, depending on whether they are symmetric (character + 1) or antisymmetric (character − 1) under rotation about the principal axis. 2D representations are labeled E, 3D representations are … Web2. 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.
