Which factor is generally responsible for high melting points? a. high intermolecular forces of attractionb. low intermolecular forces of attractionc. van der waals forcesd. london dispersion forces

A. High intermolecular forces of attraction. If there are high intermolecular forces, the molecules will need large energies to escape into the liquid. The substance will nave a high melting point.

The other options are incorrect because they are weak forces. They would cause low melting points.
