The raindrop acquires a spherical shape and ink spread over blotting paper due to:
Correct answer: A. Surface tension
- A. Surface tension
- B. Adhesive forces
- C. Viscosity
- D. Polarity
- E. Latent heat of vaporization
Explanation
A raindrop falling through the atmosphere forms a roughly spherical structure due to the surface tension of water. This surface tension is the "skin" of a body of water that makes the molecules stick together. The cause is the weak hydrogen bonds that occur between 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.
