Intermolecular forces are important for understanding how crystalline organic solids behave. These forces include hydrogen bonds, dipole-dipole interactions, and van der Waals forces. They help explain how molecules are arranged in a solid state.
The way molecules are organized in a crystal lattice depends on these forces.
For example, in substances like sugar (sucrose), strong hydrogen bonds create a stable crystalline structure.
Intermolecular forces also affect physical properties like melting and boiling points.
Substances that have stronger intermolecular attractions, such as salicylic acid, tend to have higher melting points. This is because the molecules are packed more tightly together.
Knowing about these forces helps us understand why some things dissolve in others.
Polar compounds, which have a positive and negative side, usually dissolve well in polar solvents. This is because of the strong dipole interactions between them.
In summary, intermolecular forces are key to understanding the special properties of crystalline organic solids.
