Chapter 9, Problem 136CP

Interpretation Introduction

Interpretation:

The order of the intermolecular forces and increasing boiling, melting points and enthalpy of vaporization are should be determined.

Concept Introduction:

Intermolecular forces:

• The forces involving within the molecule is called intermolecular forces thus,

Ion-dipole forces:

         The attraction forces between anion charge end with opposite partial charge is called Ion-dipole forces.

Dipole- Dipole forces:

         The attraction forces between ends of opposite partially charge in polar molecules is called Dipole- Dipole forces.

Hydrogen bond:

         The weak bond between highly electronegative atom with partially positively charged Hydrogen is called Hydrogen bonding.

London Dispersion Forces:

         The London dispersion force is the weaker force within the non polar molecules and which can be used to explain the state of the non polar molecules.

• The intermolecular forces are higher means the boiling point, melting points and enthalpy of vaporization of the compound is all so higher.
