    • The dielectric constant (symbol: ε) of a solvent is a measure of its polarity. The higher the dielectric constant of a solvent, the more polar it is.

    eg:

    The dipole moment of water is higher than that of methanol; water is more polar than methanol. One practical consequence is a covalent solute dissociates into ions to a greater extent in water than in methanol.
