Actually the hydrogen bond is simply a type of attraction which is caused by the the electronegativity difference between hydrogen and highly electronegative element like oxygen carbon nitrogen and fluorine. Intermolecular hydrogen bonding takes place between two molecules having hydrogen and electronegative element. Hydrogen is attracted by the electronegative element of another molecule for example

What is the surface tension?

At surface of a liquid will their will be no forces (forces by molecules) acting on molecules in opposite directions such that the net force between molecules (only at surface) will be zero? If exists how surface area of a liquid contracts? In the light of above concept let me explain a simple thing that
