WebMolecular compounds typically have low melting and boiling points because the attraction between molecules (which are electrically neutral) is weaker than that between electrically charged ions. Under normal conditions molecular compounds often exist as gases, liquids, or low-boiling solids. They do not conduct electricity or heat well. WebIonic compounds tend to be crystalline structures with high melting points that are water soluble. Covalent bonds are highly stable bonds with low melting points. Many covalent compounds are flexible or gaseous and are not water soluble. Metallic compounds contain freely floating electrons which allow them to conduct electricity and heat well.
