Question

When two ice cubes are pressed over each other they unites to form one cube. Which of the following forces are responsible to hold them together?

• A. Ionic interaction
• B. Van der Waal's forces
• C. Covalent interaction
• D. Hydrogen bond formation

Answer 1

The correct option is D Hydrogen bond formation

Two ice cubes, when pressed over each other, get unite due to $H-$bond formation. The electrostatic force of attraction between the positively charged hydrogen atom of one molecule and negatively charged atom of other molecule is called a hydrogen bond.

There is dipole attraction in a hydrogen bond. Ice molecules stick to each other and form a hydrogen bond.

Hence, option D is correct.
