MCQ
Bond energy of covalent $O - H$ bond in water is
- ✓Greater than bond energy of $H - $ bond
- BEqual to bond energy of $H - $ bond
- CLess than bond energy of $H - $ bond
- DNone of these
✓
Answer
Correct option: A.
Greater than bond energy of $H - $ bond
a
Hydrogen bond is a weak electrostatic force of attraction (van der Waal's attraction) between hydrogen atom and small sized, highly electronegative atoms. It is weaker than covalent bond. $O - H$ bond in water is a covalent bond and its bond energy is greater than that of hydrogen bond.
