Atom economy is…
a measure of the proportion of reactants that become useful products
2
New cards
% atom economy =
mr of desired products/mr of total products x100
3
New cards
Percentage yield is…
the mass or moles of product that should've been achieved
4
New cards
percentage yield =
actual yield/theoretical yield x100

Why is 100% yield difficult to achieve?
- Some reactants/products may be…
- Separation and purification may lead to…
- Reaction may be at equilibrium and…
- Reactants may not be…
- Side reactions may occur, leading to…
some reactants/products may be left behind in apparatus,
separation and purification may lead to loss of some product, reaction may be at equilibrium and not go to completion,
reactants may not be pure,
side reactions may occur, leading to by products
