Question

The bond dissociation energy of hydrogen bonds in water molecule is :
जल के अणु में हाइड्रोजन आबन्ध की आबन्ध वियोजन ऊर्जा है :
(1) 10.5 kJ/mol
| (2) 20.5 kJ/mol
(3) 23.3 kJ/mol
(4) 230.3 kJ/mol
​

Answer 1

bind dissociation energy of O-H bond is 23.3 KJ/mol

Answer 2

Answer:

The bond dissociation energy of hydrogen bonds in water molecules is (3) 23.3 kJ/mol.

Explanation:

Bond dissociation energy is the standard energy or enthalpy change that takes place when a particular chemical bond is cleaved by the process of homolysis.

Hydrogen bonds are present in the water where a partially positively charged hydrogen atom of one water molecule is bonded to a partially negatively charged oxygen atom of a nearby water molecule.
