Chapter 12, Problem 54A

Interpretation Introduction

Interpretation:

The intermolecular and intra-molecular forces need to be compared.

Concept introduction:

Intra-molecular forces are between atoms of molecule and intermolecular forces are between different molecules.

Answer to Problem 54A

Intra-molecular forces are those forces that hold atoms together in a molecule while intermolecular forces are those which hold different molecules together.

Intra-molecular forces are stronger than intermolecular forces.

Intra-molecular forces are due to the attraction of atoms within a molecule and intermolecular forces are due to the chemical bonding between molecules.

Explanation of Solution

These are the forces that hold the atoms and different molecules together. These are attractive forces. Due to stronger attraction of electrons of atoms within molecules these are stronger forces and these gives the physical features of a substance whereas intermolecular interactions give chemical features of a substance.
