Less hydrogen bonding in S-H compared to O-H.
Hydrogen bonding refers to the formation of Hydrogen bonds, which are a special class of attractive intermolecular forces that arise due to the dipole-dipole interaction between a hydrogen atom that is bonded to a highly electronegative atom and another highly electronegative atom which lies in the vicinity of the hydrogen atom.
- The unusually high boiling point of hydrogen fluoride among the halogen acid is due to hydrogen bonding.
- A water molecule contains a highly electronegative oxygen atom linked to the hydrogen atom. The oxygen atom attracts the shared pair of electrons more, and this end of the molecule becomes negative, whereas the hydrogen atoms become positive.
