Per NCERT, in 1808 Dalton published 'A New System of Chemical Philosophy' which COULD explain the laws of chemical combination but could NOT explain which?
AMultiple proportions
BThe laws of gaseous volumes (Gay Lussac) — and could not explain why atoms combine
CDefinite proportions
DConservation of mass
Answer & Solution
Correct answer: B. The laws of gaseous volumes (Gay Lussac) — and could not explain why atoms combine
Per NCERT, Dalton's theory explained mass laws but couldn't account for gas-volume relationships. Avogadro's distinction between atoms + molecules later resolved this.
