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...

Order the three types of intermolecular forces: dipole-dipole, London force, hydrogen bonds in terms of strength from weakest to strongest. Give a brief description of each of the different intermolecular forces. Question 24 (6 points) The boiling points for H2O (BP = 100°C) and HS (BP-60°C) are drastically different despite oxygen and sulfur being next to each other on the periodic table. Explain these differences in boiling points utilizing your labels of intermolecular forces and the relative strength of the...

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...
