Question

Maximum number of hydrogen bonding in $ {{H}_{2}}O $ is:

• A. $ 1 $
• B. 2
• C. 3
• D. 4

Answer 1

The Correct Option is D

In every $ {{H}_{2}}O $ molecule, each H-atom is involved in hydrogen bond with $ O- $ atom of other molecule, while 0-atom is involved in two hydrogen bonds with two H-atoms of other molecules. Thus, every $ {{H}_{2}}O $ molecule involves four hydrogen- bonds.
