Vedclass · Answer

(A) The strength of hydrogen bonding depends on the electronegativity of the atom bonded to hydrogen and the partial negative charge density on the electronegative atom.$HF$ has the strongest hydrogen bonding due to the highest electronegativity of fluorine.In $H_2O$,the oxygen atom is bonded to two hydrogen atoms,resulting in a higher partial negative charge density compared to $H_2O_2$,where the oxygen atoms are bonded to each other and one hydrogen atom,leading to a lower partial negative charge on each oxygen.$H_2S$ does not form significant hydrogen bonds because sulfur is not sufficiently electronegative.Therefore,the correct order of strength is $HF > H_2O > H_2O_2 > H_2S$.
