How do the melting points of ionic solids generally compare with those of molecular solids?
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.
Why do molecular solids have lower boiling points than ionic solids?
Molecular solids have lower boiling points than ionic solids because the intermolecular forces between molecules in a molecular solid are weaker than the electrostatic forces between ions in an ionic solid. As a result, less energy is required to break apart the molecular interactions and transition to the gaseous phase in molecular solids compared to ionic solids with stronger ionic bonds.
Ionic solid harder than molecular solids?
Ionic solids are typically harder than molecular solids because ionic bonds are stronger than intermolecular forces found in molecular solids. The ionic bonds in ionic solids result from the attraction between positively and negatively charged ions, contributing to their higher hardness compared to molecular solids, which are held together by weaker intermolecular forces.
Why do molecular solids usually have lower melting points than ionic solids?
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.

Are molecular solids malleable?
Molecular solids are generally not malleable. They consist of molecules held together by weak intermolecular forces, such as van der Waals forces or hydrogen bonds, which do not allow for significant deformation without breaking. Instead, when subjected to stress, molecular solids are more likely to shatter or break rather than bend or deform like metals. This brittleness is a characteristic feature of many molecular solids.

Molecular solids
How compared with the melting points of ionic compounds the melting points of molecular solids tend to be?
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.
What usually has a lower melting points than the ionic solids?
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.
What of the following usually have lower melting points than ionic solids?
Covalent compounds and molecular solids typically have lower melting points than ionic solids. This is because the forces holding covalent and molecular solids together, such as Van der Waals forces and hydrogen bonds, are generally weaker than the strong electrostatic forces present in ionic bonds. Consequently, less energy is required to break these intermolecular interactions in covalent and molecular substances, leading to their lower melting points.
Which solid is more likely to have the lowest melting point an ionic solid or molecular solid?
A molecular solid is more likely to have a lower melting point than an ionic solid. This is because molecular solids are held together by weaker intermolecular forces such as van der Waals forces, while ionic solids have strong electrostatic forces between ions.
