Theoretical yield is the amount of product predicted from

Theoretical yield is the amount of product predicted from

• A. Experimental data
• B. Stoichiometric calculations based on limiting reactant
• C. The initial amounts of products
• D. The mass of solvent

Answer: (B)

The main idea is that theoretical yield comes from stoichiometry using the limiting reactant. By applying the balanced chemical equation, you convert the amount of the limiting reactant into the amount of product that could form if the reaction goes to completion with no losses. This assumes 100% efficiency and no side reactions. Theoretical yield is thus determined purely by the stoichiometric relationship and the available limiting reactant. For example, if A + B → AB requires a 1:1 ratio and you have more B than A, A limits the amount of AB you can make, so the theoretical yield is based on how much AB would form from all of A. Other options don’t set the maximum possible product in the reaction because experimental data reflect what actually occurs (not the ideal maximum), initial product amounts don’t define how much product can be produced from reactants, and solvent mass is not involved in predicting product yield.
