Molecular solids are held together primarily by van der Waals forces, dipole-dipole interactions, and hydrogen bonding, which are weaker intermolecular forces compared to covalent or ionic bonds. These forces result from temporary fluctuations in electron density around molecules, causing them to be attracted to each other.
Solids composed of discrete molecules are kept that way because of van der Waals forces.

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.
What usually has lower melting points than ionic solids?
Molecular solids
Why do molecular solids usually have lower melting points than ionic solids?
Molecular solids typically have weaker intermolecular forces compared to the strong electrostatic forces present in ionic solids. This results in lower melting points for molecular solids as less energy is required to overcome these weaker forces and separate the molecules.
What forces hold molecular together?
London dispersion forces (also known as van der Waals forces) hold molecular solids together. or Intermolecular forces

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.
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.
If both molecular solids and network solids contain covalent bonds why do network solids have such higher melting points than molecular solids?
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.
What elements are molecular solids?
Molecular solids are composed of individual molecules held together by intermolecular forces such as van der Waals forces, hydrogen bonding, or dipole-dipole interactions. These intermolecular forces are relatively weak compared to ionic or covalent bonds, resulting in lower melting points for molecular solids. Examples of molecular solids include ice (H2O), sulfur (S8), and sugar (C12H22O11).
