The total bond energy of 2OH bond is 928 kJ/mol
Bond energy
Bond energy is the energy needed to break or form bonds. They are measured in kilojoule per mole (kJ/mol).
Total bond energy of 2OH
Since we are given that the bond energy of O-H is 464 kJ/mol and we require the total bond energy of 2OH. In 2OH, the are two O-H bonds.
So, the bond energy of the two O-H bonds will be twice that of the single O-H bond.
So bond energy of 2OH = 2 × bond energy of O-H = 2 × 464 kJ/mol
= 928 kJ/mol
So, the total bond energy of 2OH bond is 928 kJ/mol
