Vedclass · Answer

(A) The strength of a hydrogen bond depends on the electronegativity difference between the atoms involved in the bond. $F$ is the most electronegative element,followed by $O$ and $N$. In the given options,the $H-F \cdots H-F$ bond involves the most electronegative atom $(F)$ on both sides,leading to the strongest electrostatic attraction. Therefore,the $HF \cdots HF$ hydrogen bond is the strongest.
