The polarity of the above mentioned compounds in the order of least polar to the most polar can be given as follows:

• Hexane<dichloromethane<ethyl acetate<methanol.
• The above order can be explained as follows: Polarity of a mole is a measure of the overall dipole moment of the molecule. If there is an electronegativity difference between the groups forming a bond, then the bond will be polar. If the molecule is not completely symmetrical and the dipole moments of the bonds do not cancel each other, then the molecule will be polar. Higher the electronegativity difference, higher will be the dipole moment and more will be the polarity of the molecule
