How do intermolecular forces relate to the physical properties of substances? (ou will examine several physical properties of three liquids: water, ethanol, and yclohexane. The chemical structure of each chemical is in the table below. Water Ethanol Cyclohexane H- -OH H. H 1. Solubility If two liquids mix together (no layer forms), they are soluble. Try different combinations of the three liquids in a small test tube to determine which are soluble in each other. Use approximately 5 mL of each liquid. Dispose of your combinations in the "IMF Discovery" waste beaker. a. Record your observations. b. Describe the polarity (polar or non-polar) of each molecule. Which polarities mix and which do not? Use the concept of intermolecular forces to explain your observations. 2. Surface Tension

B. How do intermolecular forces relate to the physical properties of substances? You will examine several physical properties of three liquids: water, ethanol, and cyclohexane. The chemical structure of each chemical is in the table below. Water Ethanol Cyclohexane %23 H- -OH- ymmm 1. Solubility If two liquids mix together (no layer forms), they are soluble. Try different combinations of the three liquids in a small test tube to determine which are soluble in each other. Use approximately 5 mL of each liquid. Dispose of your combinations in the "IMF Discovery" waste beaker. a. Record your observations. b. Describe the polarity (polar or non-polar) of each molecule. Which polarities mix and which do not? c. Use the concept of intermolecular forces to explain your observations. 2. Surface Tension Place a drop of each liquid on a piece of wax paper. Describe each drop and measure the diameter of each drop. How many drops of each liquid can you place on the surface of a penny? a. Record your observations b. Define surface tension in your own words. Give a real-life example of when surface tension would be important or is used. c. Use the concept of intermolecular forces to explain your observations.
