The bond energy of a single O-H bond is 464 kJ/mol. If you have 2 hydroxyl groups (2 OH), you need to consider that there are 2 O-H bonds in total.
To find the total bond energy for 2 O-H bonds, you can multiply the bond energy of one O-H bond by 2:
\[
\text{Total bond energy} = 2 \times \text{bond energy of O-H}
\]
\[
\text{Total bond energy} = 2 \times 464 \, \text{kJ/mol} = 928 \, \text{kJ/mol}
\]
Therefore, the total bond energy of 2 O-H bonds is **928 kJ/mol**.
To find the total bond energy for 2 O-H bonds, you can multiply the bond energy of one O-H bond by 2:
