3a) Do liquids with weaker intermolecular forces have a higher or lower tendency to form spherical shapes?
3b) Propose a simple experiment to test your assertion
Homework Answers
Liquids with weak intermolecular force will have lower tendency to form spherical shape. Because of weak intermolecular force, cohesive force between the molecules is not very strong, as such molecules do not coalesce to form a spherical shape.

forces have a higher or lower tendency to form spherical
shapes?...

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...

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...
