Which pair shows Empirical formula CH2O?
Correct answer: D. Ethanoic acid, methanal.
- A. Methanol, Methanoic acid.
- B. Glucose, Benzene.
- C. Methoxy methane, Ethanal.
- D. Ethanoic acid, methanal.
Explanation
The actual whole number ratio of ethanoic acid is 2:4:2 and that of methanal is 1:2:1. To find empirical formula we need to calculate simplest whole number ratio which for both the compounds is 1:2:1 that is CH2O, so option D is the correct answer.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
