If you react 1.50 mL of cyclohexanol, which has a density of 0.9624 g/mL, with 1.24 mL of 85% phosphoric acid, which has a density of 1.6845 g/mL, what is the theoretical yield (in g) of cyclohexene
the theoretical yield of cyclohexene 1.24ml as phosphoric acid acts as limiting reagent.
What is Limiting Reagent?
When a chemical reaction is complete, the limiting reagent—also known as the limiting reactant or limiting agent—is the reactant that has been completely consumed.
Since the reaction cannot proceed without this reagent, the amount of product that can be produced is constrained.
Excess reagents or excess reactants are any reagents that are present in amounts greater than those necessary to cause a reaction with the limiting reagent (sometimes abbreviated as "xs").
The theoretical yield is the quantity of product obtained when the limiting reagent reacts completely, hence it is necessary to identify the limiting reagent in order to compute the percentage yield of a reaction.
