Vedclass · Answer

(D) Key Idea: The strength of hydrogen bonding is directly proportional to the electronegativity difference between the $H$-atom and the atom to which it is covalently bonded,as well as the electronegativity of the atom forming the hydrogen bond.Since the electronegativity of $F$ is the highest among $N$,$O$,and $F$,the $H-F$ bond is the most polar,and the interaction in $F-H \cdots F$ is the strongest.Therefore,option $D$ is the correct answer.
