The electrostatic force between the positive ions and the negative ions are very strong, so it requires a large amount if energy to break them. The attractive force between covalent molecular is weak, so less heat energy is required to break it.
Covalent solids and molecular solids typically have lower melting points than ionic solids. This is because the intermolecular forces holding covalent and molecular solids together are generally weaker than the electrostatic forces binding ionic solids, resulting in lower energy requirements for melting.
Molecular solids
The melting points of molecular solids are lower compared to ionic compounds. This is because molecular solids are held together by weaker intermolecular forces, such as van der Waals forces, which are easier to overcome than the strong electrostatic forces present in ionic compounds.
Ionic solids generally have higher melting points compared to molecular solids. This is because in ionic solids, strong electrostatic forces hold the ions together in a rigid lattice structure, requiring more energy to break these bonds and melt the substance. Molecular solids, on the other hand, are held together by weaker intermolecular forces, resulting in lower melting points.
Network solids have a three-dimensional structure with strong covalent bonds throughout, leading to a higher melting point compared to molecular solids which have weaker intermolecular forces. In network solids, a larger amount of energy is required to break the extensive network of covalent bonds, resulting in a higher melting point.

Covalent compounds, molecular solids, and metallic solids typically have lower melting points than ionic solids. Covalent compounds consist of molecules held together by weaker van der Waals forces, while molecular solids are composed of discrete molecules that interact through intermolecular forces. Metallic solids, while having variable melting points, often do not reach the high melting points characteristic of ionic solids due to their bonding nature.
Ionic compounds have a higher melting point.
Molecular solids
Covalent network solids and molecular solids typically have lower melting points than ionic solids. Covalent network solids, like diamond or graphite, have strong covalent bonds throughout the structure, but their overall melting points can vary based on the specific material. Molecular solids, made up of discrete molecules held together by weaker intermolecular forces (such as van der Waals forces or hydrogen bonds), generally have much lower melting points compared to the strong ionic bonds found in ionic solids.

Consequently, less energy is required to break these intermolecular interactions in covalent and molecular substances, leading to their lower melting points.
