Homework Answers
Generally we are using an ether as the best and potential solvent to extract organic compounds from the mixture.
If you want to extract a compound from water then Hexanes is the better choice because hexane has less solubility in water than that of ether.
Potential solvent for extracting an organic compound from water is Hexane.
