Solution
Hydrogen bonding:
Dipole-Dipole interaction between a hydrogen atom attached to an electronegative atom and another electronegative atom that lies close to the hydrogen atom is called hydrogen bonding.
In water molecules (), for example, hydrogen covalently bound to the electronegative oxygen atom show interactions with the oxygen atom of another molecule, hence, hydrogen bonding occurs in water molecules.
Hydrogen bonding or :
Higher the electronegativity of the atom attached to hydrogen, more is the polarization of the molecule and hence strong hydrogen bonding.
The hydrogen atom becomes positively charged and the electronegative atom becomes negatively charged due to polarization.
(Hydrogen bonding in water)
In the case of and oxygen is more electronegative than Sulphur therefore polarization occurs more in the case of and hence has more hydrogen bonding as compared to .
Therefore S-H has less H-bonding as compared to O-H.
