NEET Biology: Chemical Bonding questions with solutions

Q1. Cohesive force of water is due to

1. 0 -bonds
2. OH - bonds
3. S-bonds
4. H-bonds

Answer: H-bonds

Water molecules are held together by hydrogen bonding, which arises because oxygen is highly electronegative and creates a polar O–H bond. This makes the hydrogen of one molecule attract the oxygen of another, producing cohesion.
