In which of the following the hydrogen bond is strongest:

In which of the following the hydrogen bond is strongest:

(a) F-H—F

(b) O-H—S

(c) S-H—F

(d) F-H–O

Answer: (a)

Explanation: Hydrogen Bonding

The formation of hydrogen bonds, a sort of attractive intermolecular force induced by the dipole-dipole interaction between a hydrogen atom bound to a strongly electronegative atom and another strongly electronegative atom nearby, is referred to as hydrogen bonding.

The strongest bond is F-H-F.

The interaction between the electronegativity of the bound atom and hydrogen determines the strength of the hydrogen bond. Fluorine is the most electronegative element in the periodic table. As a result, the F-H-F bond will be the most powerful H bond.

Hydrogen Fluoride Hydrogen Bonding

Fluorine, which has the highest electronegativity, forms the strongest hydrogen bond.
