Questions and Answers
Explain the molecular symmetry of water (H2O) and the bond angle between the central oxygen atom and the hydrogen atoms.
Water (H2O) has C2v molecular symmetry and a bond angle of 104.5° between the central oxygen atom and the hydrogen atoms.
Explain the traditional and advanced bonding models discussed to provide a comprehensive bonding model for H2O.
Several traditional and advanced bonding models such as simple Lewis and VSEPR structure, valence bond theory, molecular orbital theory, isovalent hybridization, and Bent's rule are discussed to provide a comprehensive bonding model for H2O.
Describe the Lewis structure of H2O and the nature of the bonds it describes.
The Lewis structure of H2O describes the bonds as two sigma bonds between the central oxygen atom and the two peripheral hydrogen atoms.
Explain the significance of Bent's rule in rationalizing the various electronic and physical properties and features manifested by the peculiar bonding arrangements of H2O.
