Percentage yield and atom economy Flashcards
1
Q
Percentage yield equation
A
amount of product made/ max amount of product possible x 100
2
Q
Why are percentage yields never 100%
A
maybe reversible, product is lost, product is left in apparatus, product no separated from by-products, reactants are impure producing unexpected products
3
Q
Atom economy definition
A
amount of reactants that end up as useful product
4
Q
Atom economy equation
A
RFM of desired product/RFM of all reactants x 100
5
Q
Reaction pathway considerations
A
atom economy, % yield, sustainability - energy costs, amount of waste, usefulness of by-products - rate of reaction, equilibrium position
