Question

Dalton's Atomic theory could not explain which of the following?

1. A. Law of conservation of mass
2. B. Law of constant proportion
3. C. Law of multiple proportion
4. D. Law of gaseous volume (Correct answer)

Correct Answer

Option D — Law of gaseous volume

Detailed Solution & Explanation

The correct answer is Law of gaseous volume.

Key Points

• Dalton's atomic theory successfully explained the laws of chemical combination — conservation of mass, constant proportion, and multiple proportion.
• It could not explain Gay-Lussac's law of gaseous volumes (later accounted for by Avogadro's hypothesis).
