First we’ll review some important definitions.Yield–Simply means the amount of a particular
product formed in a chemical reaction
Theoretical Yield
Theoretical Yield–(also called predicted yield)
Theoretical Yield–(also called predicted yield) is the amount of product predicted by a stoichiometric calculation.
In other words, if we’re given the amounts of reactants and asked to use stoichiometry to find the mass of a product, then we are finding the theoretical (or predicted ) yield of that product.
For various reasons, when a reaction is carried out in a real physical setting, like a lab or an industrial site, we don’t always get the amount of a product predicted.

Actual yield
For various reasons, when a reaction is carried out in a real physical setting, like a lab or an industrial site, we don’t always get the amount of a product predicted.
Actual yield – the amount of a product that is actually obtained in a reaction.

Theoretical Yield
If the actual yield of a particular product was equal to the theoretical, or predicted yield, then the percent yield would be 100%.
