atom econ and theoretical yield Flashcards
1
Q
why dont most organic reactions produce as much product as they should theoretically
A
1) incomplete reactions
2) presence of competing side- reactions
3) mechanical losses (during separation + purification)
2
Q
percentage yield
A
relative success of an organic reaction is measured by its percentage yield
3
Q
percentage yield=
A
actual yield (g)/ theoretical yield (g) x 100
4
Q
what is atom economy
A
the idea to judge how effective a chemical reaction is in terms of how much material is wasted or not
5
Q
ATOM ECONOMY=
A
molecular mass of product/sum of the molecular mass of all product X 100
6
Q
the higher the atom economy
A
the lower the amount wasted
