Question

Polar liquids have higher boiling point than comprable non polar liquids explain

Answer 1

The polar liquid has a higher boiling point because they are loosely held or are not bonded. It includes all the other shapes with non-bonding pairs. Examples- Air and water. 
But the non-polar liquid has the least boiling point as they are held together by the weak van der waals forces.It includes the shapes that don't have a non-bonding pair. Examples-Methane and Chloroform. 

So, as the non-polar liquid is weaker in nature as compared to the polar liquid, thus it has a low-melting point. 

Answer 2

Answer:

polar molecules

Explanation:

Substances with hydrogen bonding, an intermolecular force, will have much higher melting and boiling points than those that have ordinary dipole-dipole intramolecular forces. Non-polar molecules have the lowest melting and boiling points, because they are held together by the weak van der Waals forces.
