Class 11Chemistry8-3.Organic Chemistry : Purification and characterizationPurification of Organic Compounds
EasyIn the differential extraction method using a separating funnel,two layers are formed. What is the difference in the mixture before shaking the solution and at the end of the process?
(N/A) Initially,the organic compound is primarily dissolved in the aqueous layer.
After shaking and allowing the layers to separate,the compound is distributed between the two solvents based on its partition coefficient,resulting in a higher concentration in the organic solvent layer and a lower concentration in the aqueous layer.
