In solvent extraction ether is used to separate products of organic synthesis from________________?
Correct answer: A. water
- A. water
- B. iodine
- C. hydrochloric acid
- D. gases
Explanation
Ether is immiscible with water and dissolves many organic products, so the organic products can be transferred into the ether layer and separated from water. A student may choose hydrochloric acid because acid is often present in reaction mixtures, but ether extraction specifically commonly separates organic compounds from an aqueous phase.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
