The process of separation of an organic compound from its aqueous solution by shaking with a suitable solvent is termed solvent extraction or differential extraction.

The organic compound present in the aqueous layer moves to the organic solvent because

• A. the organic substance is more soluble in the organic solvent
• B. organic compound being lighter moves in the upper layer
• C. organic solvent is insoluble in water hence organic compound moves up
• D. from the supersaturated aqueous solution the solute starts diffusing
