Question

the bond dissociation energy of hydrogen bonds in water molecules​

Answer 1

Answer:

For example, dissociation of HO–H bond of a water molecule (H2O) requires 118.8 kcal/mol (497.1 kJ/mol). The dissociation of the remaining hydroxyl radical requires 101.8 kcal/mol (425.9 kJ/mol). The bond energy of the covalent O–H bonds in water is said to be 110.3 kcal/mol (461.5 kJ/mol), the average of these values.

Explanation:

Answer 2

The “bond dissociation energy” of the hydrogen bonds in the molecules  of water is about ‘23 kJ/mol’.

Explanation:

• Hydrogen bond is a type of attraction called as electrostatic attraction between “a hydrogen atom” and “an electron negativity atom” that is covalently bonded to the hydrogen atom.

• If hydrogen bond is formed in between atoms within a molecule is called intra-molecular hydrogen bond and if hydrogen bond is formed in between which are in different molecules are called inter hydrogen bond. The bond dissociation energy of hydrogen bonds are vary for different molecules.

• The “bond dissociation energy” of the hydrogen bonds in the molecules  of water is about ‘23 kJ/mol’.

• The “bond dissociation energy” of covalent bonds in water molecules about 470 kJ/mol.
