Molecular Compounds have low melting and boiling point as compare to the Ionic Compounds. Molecular Compounds can be in any state, solid, liquid or gas at room temperature, whereas Ionic Compounds are always in solid state with forming crystalline appearance.
Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent ormolecular compounds form when elementsshare electrons in a covalent bond to form molecules.
