Answer on Physical Chemistry Question for vijay

Question #4851
what are the factors on which strength of hydrogen bond depends.is it stronger in water or hydrogen fluoride.
Expert's answer
From the equation for the dipole-dipole interaction we see that the interaction
energy depends on the square of the partial charges. So if we increase the
polarization between the atoms involved in the hydrogen bond, the hydrogenbond
should become much stronger. Fluorine is the most electronegative element
(3.98on the Pauling scale) and because of this fluorine forms some of the
strongest hydrogen bonds.
