Question

The hydrogen bonds are encountered in $\mathrm{HF}, \mathrm{H}_{2} \mathrm{O}$, $\mathrm{NH}_{3}$ and $\mathrm{HF}_{2}^{-}$. The relative order of energies of hydrogen bonds is\

(d): Higher is the electronegativity, stronger is the H -bond. Fluorine has more electronegativity among the given elements. In $\mathrm{HF}_{2}^{-}$, there are two fluorine atoms that results into even stronger H -bonding.\
