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.
Ionic bonds would affect melting point the least. This is because ionic bonds are typically much stronger than the other intermolecular forces mentioned, making them less susceptible to changes in temperature that affect the melting point.
London dispersion forces would affect the melting point the least as they are generally weaker than dipole-dipole and hydrogen bonding forces.
IMF (intermolecular forces) affect the boiling and melting points of a substance by influencing the strength of the bonds between molecules. Stronger IMFs lead to higher boiling and melting points because more energy is required to overcome these forces. Weaker IMFs result in lower boiling and melting points as less energy is needed to break the intermolecular interactions.
Melting and boiling points are higher when intermolecular forces (such as hydrogen bonding, dipole-dipole interactions, or London dispersion forces) are stronger. These forces hold molecules together, so more energy is required to overcome them and change the state of the substance. Conversely, weaker intermolecular forces result in lower melting and boiling points.

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 bonds would affect melting point the least. This is because ionic bonds are typically much stronger than the other intermolecular forces mentioned, making them less susceptible to changes in temperature that affect the melting point.
These are the hydrogen bonds between molecules.
Van der Waals forces
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.

Hydrogen bonding, which is the strongest of the intermolecular forces.

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.
Van der Waals forces would affect the melting point the least among the given intermolecular forces. These forces are generally weaker than ionic bonds, hydrogen bonds, and dipole-dipole interactions, resulting in lower energy requirements to overcome them. Consequently, substances primarily held together by Van der Waals forces tend to have lower melting points compared to those influenced by stronger interactions.
