Indicate the incorrect statement from the following
Correct answer: B. Actual yield is always greater than theoretical yield
- A. A limiting reagent is consumed at the end of the reaction
- B. Actual yield is always greater than theoretical yield
- C. Stoichiometric calculation can be only done if no side reaction happens
- D. The empirical formula in molecular formula of some of the compounds are same
Explanation
Actual yield is less than theoretical yield due to the following reasons i) side reactions may produce by-products ii) some reactions are reversible iii) mechanical loss takes place due to filtration, distillation, and separation by separating funnel, washing and crystallisation etc.

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.
