How many hydrogen bonds can a water molecule form with other water molecules?
Correct answer: B. 4
- A. 3
- B. 4
- C. 2
- D. 1
Explanation
A water molecule can form 4 hydrogen bonds with another water molecule at most. This is because a water molecule has two lone pairs of an oxygen atom and two hydrogen atoms.The 2 hydrogen atoms form a hydrogen bond with a lone pair in oxygen of 2 other water molecules and the oxygen atom, using its 2 lone pairs forms 2 hydrogen bonds with 2 other water molecules.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
