In general covalent bonds determine: molecular shape, bond energies, chemical properties, while intermolecular forces (non-covalent bonds) influence the physical properties of liquids and solids. You can change your ad preferences anytime. Water vapor, liquid water and ice all have the same chemical properties, but their physical properties are considerably different.
