Chemistry help please!!!?

chemists always report the yield (as a %) when they perform a reaction,because it shows how efficient the reaction is a method of preparing the desired product.



when it would be important to report both the total yield and the isolated yield of a reaction?

I never heard about isolated but I could think about something like this if the reaction process included, for example, two reactions.



So first reaction will have a yield of say 90% and the second 10% and the total will be 9%. Then I will be interested to know why it is only 9% and reporting both reaction efficiency will help.

never heard of term isolated yield.



sure you didn't make it up?
