Vedclass · Answer

(C) The strength of a hydrogen bond depends on the electronegativity of the atoms involved in the bond. The greater the electronegativity difference between the hydrogen atom and the atom it is bonded to, the stronger the hydrogen bond will be. Fluorine $(F)$ is the most electronegative element in the periodic table. Therefore, the $F-H...F$ bond is the strongest among the given options because fluorine has the highest electronegativity compared to oxygen $(O)$ and sulphur $(S)$. The electronegativity order is $F > O > S$.
