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.
Molecular shapes and VSEPR theory. There is a sharp distinction between ionic and covalent bonds when the geometric arrangements of atoms in compounds are considered. In essence, ionic bonding is nondirectional, whereas covalent bonding is directional.
