Question

Which of the following attractive forces would result in the lowest melting point?

A. Van der Waals forces
B. Dipole-dipole attractions
C. Hydrogen-bonding forces
D. Ionic electrostatic attractions

Answer 1

van der Waals forces, because this is the weakest intermolecular force. there is less attraction within the molecules which cause low melting point.

Answer 2

Answer: A. Van der Waals forces

Explanation: Vander Waals forces are the forces which are the weakest intermolecular forces of attraction. It is the forces of attraction between the non polar molecules.

Thus these are the forces which would result in the lowest melting point.

Hydrogen bonding forces and Ionic electrostatic forces are the strong forces of attraction which will result in the higher melting point.
