Concept explainers
Interpretation: Basic features of the VSEPR model should be explained. Also the reason for why the decreasing order of magnitude of repulsion is from lone pair - lone pair, then lone pair - bonding pair and finally bonding pair - bonding pair should be explained.
Concept Introduction: Molecular geometry of a molecule can be predicted by valence-shell electron-pair repulsion (VSEPR) model where atoms are arranged in such a way that the repulsion between lone pairs and bond pairs of electron on the central atom or ion should be minimalized. Because of this electrostatic repulsion there is some deviation in regular geometry. The decreasing order of magnitude of repulsion is, lone pair - lone pair, then lone pair - bonding pair and finally bonding pair - bonding pair
