Which of the following describes the proper technique for performing a simple extraction?

The proper technique for performing a simple extraction involves mixing the organic compound with a solvent and shaking the mixture in a separating funnel. This process allows the organic compound to distribute between the two immiscible phases—the organic solvent and the aqueous phase—based on its solubility in each solvent. By shaking, the two phases come into contact, enhancing the interaction and allowing for the transfer of the desired solute from one phase to another.

In a separating funnel, after shaking, the mixture is allowed to settle so that the two layers form distinctly. This separation is crucial because it allows for the careful removal of one layer without disturbing the other, which is essential for achieving a clean separation of the organic compound from impurities or undesired components.

Heating the mixture to evaporate the solvent may be a part of certain procedures, but it doesn't constitute the extraction technique itself. Adding water to the organic compound and filtering does not accurately describe an extraction method, as it does not facilitate the separation of components based on solubility in two different solvents. Lastly, employing a centrifuge can aid in separating components, but it is not the standard method taught for simple extraction, which relies more on the differences in solubility and density between the two phases rather than mechanical
