how do covalent compound differ from ionic compounds in solubility, melting point and boiling point
Answers
Melting-- In order to melt an ionic compound, it is necessary to break ionic bonds. Therefore, ionic compounds usually have high melting points. To melt a covalent compound, it isn’t necessary to break bonds. It is only necessary to overcome the much weaker intermolecular forces that hold the particles together. Covalent compounds generally have much lower melting and boiling points than ionic compounds.
Solubility – Ionic compounds tend to be soluble (or dissolve in) water because water is a polar compound that can exert enough force to overcome the ionic bond and cause the ions to go into solution. In general covalent compounds are less soluble in water. The tendency of compounds to dissociate or ionize in water tells a great deal about the way in which bonds hold the compound itself together. Covalent compounds aren't usually very soluble in water.
