How is a high atom economy good for profits?
-decreasing amount of reactants wasted, so money is saved
How is a high atom economy good for the environment?
-saves resources as resources are not wasted, and stops reactions from being unsustainable
What is percentage yield?
- comparison of actual yield and predicted yield
- evaporation
- filtraton
- transferring liquids
- not all reactants react to make product
What is atom economy?
-tells you how much mass of reactants was wasted
Why a yields never 100%?
-some product or reactant always lost along the way
How does transferring liquids cause a loss of yield?
- may lose some liquid when transferring from one container to the next, even if nothing spills
- some always gets left behind on inside surface of last container
What are the benefits of a high percentage yield?
- reduce waste products
- reduce costs
How does filtration reduce percentage yield?
- filtering liquid to remove solid particles you always lose a bit of liquid or solid
- if you want to keep liquid, you lose the bi that remains with the solid and filter paper
- if you want to keep solid, some of it always gets left behind when you scrape it off filter paper
How does evaporation reduce percentage yield?
- liquids evaporate all the time
- even more when heated
How do not all reactants reacting reduce percentage yield?
-reversible reactions turn products back to reactants while the reaction is going on, so yield will never be 100%
