Hydrogen bonding causes the collective ground state of liquid water to have an energy lower than the ground state found in single gaseous molecules. The water hydrogen bond is a weak bond, never stronger than about a twentieth of the strength of the O-H covalent bond.

Bond energy of covalent O-H bond in water is:a)Less than or equal to b...
Bond energy refers to the amount of energy required to break a bond between two atoms in a molecule. It is typically measured in kilojoules per mole (kJ/mol). In the case of water (H2O), the covalent O-H bond represents the bond energy between the oxygen atom and one of the hydrogen atoms.
The bond energy of the O-H bond in water is greater than the bond energy of a hydrogen bond.
Explanation:
The covalent O-H bond in water is a strong bond that holds the hydrogen atom to the oxygen atom. This bond is formed through the sharing of electrons between the atoms. The bond energy of the O-H bond in water is approximately 464 kJ/mol.
On the other hand, a hydrogen bond is a weak bond that occurs between a hydrogen atom in a polar molecule and an electronegative atom (usually nitrogen, oxygen, or fluorine) in another molecule. It is an attractive force between the partially positive hydrogen atom and the partially negative atom in the other molecule. Hydrogen bonds are responsible for many important properties of water, such as its high boiling point and surface tension.
The bond energy of a hydrogen bond is typically much weaker than that of a covalent bond. The energy required to break a hydrogen bond is generally in the range of 10-40 kJ/mol. This is significantly lower than the bond energy of the O-H bond in water.
Therefore, the bond energy of the covalent O-H bond in water is greater than the bond energy of a hydrogen bond.
