PART IV. MISCIBILITY OF TWO LIQUIDS 1. For the first two liquids in Table IV-B (the solvents in the miscibility tests), use the molecular structures provided in the Introduction to identify each liquid as polar or nonpolar. Put an X in the appropriate column. 2. For the remaining liquids in Table IV-B, determine if they are primarily polar, primarily nonpolar, or both polar and polar based on your observations in Table III-A and based on the polarity of the solvent....
7). a). Is the acetone molecule non-polar or polar? Circle. Non-polar Polar b). Sketch pictures of the intermolecular forces that would occur between the molecules of acetone and the molecules of 2- propanone if you have a mixture of the two liquids. What would be the main type of IMF that is responsible for the attraction? (Give a name for the IMF). c). The pentane molecule and the 2-pentanone molecule both have five carbon atoms on their structures. Why 2-pentanone...
2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...
1a. Please review Data Table #2 and check the information that has been filled in for accuracy/fill in the remaining information that has not been completed. 1b. Based on your temperature measurements, which molecule seems to have the strongest intermolecular forces? What is/are the force(s) in that particular molecule? Use your data to explain your reasoning. 1c. Which seems to have the weakest intermolecular forces? What is/are the force(s) in that particular molecule? Use your data to explain your reasoning....
INTERMOLECULAR FORCES INTRODUCTION LEARNING OBJECTIVES To relate the effecet of intermolecular forces on relative melting points and vapour pressures of some organic substances THEORY Weak attractive forces that occur between individual molecules in substances are called intermolecular forces. These include London dispersion forces, dipole-dipole forces and hydrogen-bonding forces. Collectively, the three types of intermolecular forces are referred to as Van der Waals forces. These attractive forces are much weaker than the chemical bonds between atoms in a molecule. Note that...
