Rate of evaporation of petrol is greater than that of water at room temperature because:
Correct answer: A. petrol molecules do not have any hydrogen bond
- A. petrol molecules do not have any hydrogen bond
- B. petrol is an organic compound
- C. water molecules have small size
- D. petrol molecules have greater size
Explanation
Water molecules form extensive hydrogen bonds, which hold them together strongly and reduce evaporation. Petrol lacks this hydrogen-bond network, so its molecules escape more readily at room temperature.
