Question

The number of hydrogen bonds formed by a water molecule at normal conditions is:

• A. 1
• B. 2
• C. 3
• D. 4

Hint:

Water molecules form 2 hydrogen bonds at normal conditions due to the bent shape and the ability of the oxygen atom to act as a hydrogen bond acceptor and the hydrogen atoms to act as donors.

Answer 1

The Correct Option is B

The bent geometry of water molecules, caused by two lone pairs on the oxygen atom, facilitates hydrogen bonding with adjacent water molecules. A single water molecule can participate in two hydrogen bonds: one involving a hydrogen atom from a different water molecule, and another involving the oxygen atom of a separate water molecule.Final Answer: Under standard conditions, a water molecule forms 2 hydrogen bonds.
