Atom economies and percentage yields Flashcards
1
Q
What is the atom economy of a reaction?
A
It is the theoretical percentage of how many atoms are wasted in the reaction.
2
Q
Why do we calculate atom economy?
A
To find the practical efficiency.
3
Q
What is the equation for atom economy?
A
Atom economy = (Mr of desired product/ Mr of total products) x100
4
Q
What does the percentage yield tell us?
A
The practical efficacy of the process and how much is lost by:
Obtaining the product
Result of the reactions that didn’t finish.
5
Q
Why is atom economy and percentage yield just theory?
A
This is because you will never get exactly what you’re supposed to get due to precipitate.
6
Q
What is the percentage yield equation?
A
Percentage yield = actual yield/ theoretical yield x100
