Question

Cohesive force of water is due to

• A. O -bonds
• B. OH - bonds
• C. S-bonds
• D. H-bonds

Answer 1

Answer: (D)

H-bonds

• Cohesion force is the strong force of attraction that exist between the same molecules.
• Cohesive force of water is due to the hydrogen bond between the water molecules.
• It allows the liquid molecules to resist separation. Cohesion holds hydrogen bonds together to create surface tension on water. The electronegative oxygen forms a hydrogen bond with the hydrogen atom.
  

So, the correct answer is option D.
