(a) Interpretation: For the given molecule, both the molecular structure and the bond angle that exits around the central atom are to be stated. Concept Introduction: VSEPR theory is an important model that is frequently used in chemistry to decide the shape and geometry of the molecules. VSEPR model is the extension of Lewis model. As the Lewis model is not able to explain the shape of the molecules. In terms of electron density it is given that both the bonding electrons as well as lone pair of electrons holds the shape of the molecule. The shape in VSEPR model gives specific angles between the bonds for the corresponding shape and these angles are known as bond angles.
