The intermolecular force that would cause the highest melting point is hydrogen bonding. This strong type of dipole-dipole interaction occurs between molecules that have hydrogen atoms bonded to highly electronegative elements like nitrogen, oxygen, or fluorine. The strength of hydrogen bonds requires more energy to break, resulting in a higher melting point compared to other intermolecular forces such as van der Waals forces or regular dipole-dipole interactions.
Hydrogen bonding, which is the strongest of the intermolecular forces.
Van der Waals forces
These are the hydrogen bonds between molecules.
The intermolecular force that most significantly affects the melting point of a substance is hydrogen bonding. Substances with strong hydrogen bonds typically have higher melting points because these bonds require more energy to break. In contrast, substances with weaker intermolecular forces, such as Van der Waals forces or dipole-dipole interactions, generally have lower melting points. Therefore, the presence and strength of hydrogen bonds can greatly influence the melting point of a compound.
Ionic bonding is the strongest type of intermolecular force and is responsible for the high melting points of solid salts. In ionic bonding, positive and negative ions are held together by strong electrostatic forces of attraction.

The cause is just this weak intermolecular force, ease to be broken.

Hydrogen bonding
London dispersion forces would affect the melting point the least, as they are the weakest intermolecular force. They are caused by temporary fluctuations in electron density, making them generally less influential on physical properties compared to other intermolecular forces such as hydrogen bonding or dipole-dipole interactions.
The melting point of a substance is primarily influenced by the strength of intermolecular forces present in its structure. Stronger intermolecular forces, such as hydrogen bonding or ionic interactions, typically result in higher melting points because more energy is required to overcome these forces during the transition from solid to liquid. Conversely, weaker forces like van der Waals (dispersion) forces lead to lower melting points. Thus, the type and strength of intermolecular forces play a crucial role in determining the melting point of a substance.
Melting points are significantly affected by intermolecular forces such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces. Substances with strong intermolecular forces, like hydrogen bonds, typically have higher melting points due to the greater energy required to overcome these interactions. Conversely, substances with weaker forces, such as London dispersion forces, generally have lower melting points. Therefore, the type and strength of intermolecular forces present in a substance play a crucial role in determining its melting point.
The intermolecular force that affects melting point the most is hydrogen bonding. Substances that exhibit hydrogen bonding, such as water or alcohols, typically have higher melting points compared to those that rely on weaker forces like van der Waals or dipole-dipole interactions. This is because hydrogen bonds are strong enough to require considerable energy to break, thereby raising the melting point. Overall, the presence and strength of hydrogen bonds play a significant role in determining the melting point of a substance.
