Chapter 12, Problem 88A

Interpretation Introduction

Interpretation:

The three types of intermolecular force must be listed.

Concept introduction:

Intermolecular forces are active among molecules.

Answer to Problem 88A

Three types of intermolecular force are dipole-dipole, hydrogen bonding and dispersion force.

Explanation of Solution

Dipole-dipole interaction is active in molecules with permanent dipole moment. Positive pole of one dipole interacts with negative pole of another dipole.

Hydrogen bonding is present in molecule with small electronegative atoms like N, F and O when bonded with H.

Dispersion force or induced dipole is present in molecules which don’t have permanent dipole moment.

Conclusion

Three types of intermolecular forces are dipole-dipole, hydrogen bonding and dispersion force.
