Question

what is the molecular geometry for two electron groups (as in co₂)? linear bent

Explanation:

The VSEPR (Valence - Shell Electron - Pair Repulsion) theory is used to determine molecular geometry. For a molecule with two electron groups (like \(CO_2\)), the electron groups (in \(CO_2\), these are the two double bonds between \(C\) and \(O\)) will arrange themselves to be as far apart as possible. The farthest apart two electron groups can be is in a linear arrangement (\(180^{\circ}\) apart). A bent geometry occurs when there are three electron groups (e.g., \(H_2O\) has two bonding pairs and one lone pair, total three electron groups).

Answer:

linear
