Question

Dalton's atomic theory is contradicted by the formula of sucrose. Justify the statement​

Answer 1

Answer:

Dalton’s atomic theory states that atoms of different elements combine together in simple whole number ratio. In the formula of C₁₂H₂₂O₁₁ the carbon, hydrogen and oxygen combine in whole number ratio but the ratio is not simple.

Answer 2

• Dalton's atomic theory is contradicted by the formula of sucrose.
• According to Dalton's atomic theory, 'Atoms of different elements combine together in simple whole-number ratio.'
• In the formula of Sucrose (C₁₂H₂₂O₁₁), the elements of Carbon, Hydrogen, and oxygen combine together in the simple whole-number ratio.
• The contradiction to the fact is that the ratio is not the same.

Hence, this is the drawback of Dalton's Atomic theory.
