(a)
Interpretation:
The electron geometry, molecular geometry, and bond angle about the charged atom in the given molecule is to be identified.
Concept introduction:
The VSEPR chart depicts the electron and molecular geometry on the basis of numbers of electron groups. The Electron geometry about an atom describes the orientation of a group of electrons around it. A lone pair of electrons, a single bond, a double bond, a triple bond each is considered as one group of electrons. Molecular geometry describes the arrangement of surrounding atoms about a particular atom. Molecular geometry is governed by electron geometry of an atom. If all the electron groups around an atom are bonds, then the molecular geometry will be the same as electron geometry. The electron and molecular geometry about a particular atom will be different when one or more of the electron group is lone pair. The bond angle is the angle between two bonds originating from the same atom in a covalent molecule or ion. The bond angle depends on the molecular geometry around the atom.
