All ionic compounds and heteroatomic molecules have charge separation due to electronegativity difference. This charge separation generate dipole moment in molecules.    How charge separation occurs in molecules?    When atoms in molecules have different electronegativity values, more electronegative atoms attracts the bonded pair more towards itself it results in the formation of two opposite charged poles in molecules.In this way charge separation occurs.     There will be strong dipole moment if there is more charge separation in molecules. The charge separation depends on the electronegativity value. Its mean The magnitude of  dipole moment depends on the electronegativity difference. The three parameters - charge separation, electronegativity and dipole moment- are directly interdependent.   DEFINITION : When two opposite unit electrical charges(q) are separated by a distance(r) a dipole created and amount of  dipole is calle...
