Question

Which hydrogen bond is the weakest?

Answer 1

• Hydrogen bonding is a dipole-dipole interaction which arises when a covalently bonded highly electronegative element is in vicinity of a hydrogen atom.
• Hydrogen bonds can be formed with elements such as Nitrogen, Oxygen, Fluorine, Sulphur, etc.
• The relative strength of hydrogen bonds can be determined by the electronegativity of the atom the bond formation is going to occur.
• Higher the electronegativity, stronger will be the hydrogen bond and similarly lower electronegativity leads to weaker hydrogen bond.
• Among the mentioned Sulphur is the least electronegative and thus the hydrogen bond formed with Sulphur will be the weakest.
