Concept introduction:
VSEPR theory stands as Valence Shell Electron Pair Repulsion Theory. It helps to predict the molecular shape or geometry of the molecule with the help of the number of bond pair or lone pair present in it. According to VSEPR theory, the presence of lone pair on the central atom of molecule causes deviation from standard molecular geometry. This is because of the repulsion between lone pairs and bond pairs of the central atom of the molecule. The order of repulsion is:
Lone pair-lone pair > lone pair-bond pair > bond pair-bond pair
Based on the number of lone pair and bond pair, the molecular geometry can be determined with the help of below table.
| Total number of electron pairs | Bond pair | Lone pair | Geometry |

Complete the following table. The only density needed is already given. Show your
calculations in a neat and easy-to-follow manner in the space below the table. All units
should be included and significant figures should be given close attention. Be sure to notice
that the amount of material should be in millimoles rather than moles, and the theoretical
mass of the product should in milligrams rather than grams.
