Question
Use the dropdown menus to indicate whether a solvent pair could be used successfully in a mixed-solvent recrystallization.
a-hexanes and water [ Select successful or unsuccessful ]
b-chloroform and diethyl ether [ Select successful or unsuccessful ]
c-acetone and methanol [ Select successful or unsuccessful ]
Expert Solution
Step 1
Ideal properties of mixed solvents in recrystallization:
1) The compound should be readily soluble in one solvent and insoluble in another solvent at the room-temperature.
2) Two solvents must be completely miscible with each other and should have difference in polarity.
