Homework Answers
a)
Kr is a single element.
It will have only dispersion forces
b)
S8 is non polar.
It will have only dispersion forces
c)
NH3 is polar due to lone pair on N and it ha trigonal pyramidal
shape.
So, it is polar.
It will have dispersion forces and dipole-dipole forces
d)
CH3OH is polar and can also form hydrogen bonding as it has H
attached to O.
So, forces here are dispersion forces, hydrogen bonding and
dipole-dipole forces

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...

h of the following statements is NOT true? London dispersion forces are present in all substances but are the only significant intermolecular forces in nonpolar substances. ) The density of the liquid state of a substance is greater than the density of its gaseous state. The thermal energy in a liquid allows the atoms within molecules to completely overcome the attractions between them so they flow. Most liquids can be converted to a gas by reducing pressure and/or heating. The...
