These are the hydrogen bonds between molecules.
Van der Waals forces
Hydrogen bonding, which is the strongest of the intermolecular forces.
Yes, because the melting point depends on the strength of the intermolecular forces, which are different for different molecules and compounds. Stronger intermolecular forces mean a higher melting point.
Generally, as the carbon chain length increases, the melting point of a compound also tends to increase. This is because longer carbon chains result in stronger intermolecular forces, such as London dispersion forces, leading to a higher melting point. Shorter carbon chains have weaker intermolecular forces, so they typically have lower melting points.
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.
