\[\ce{H2O}\]
\[\ce{HI}\]
\[\ce{H2S}\]

उत्तर
\[\ce{H2O}\]
Explanation:
Hydrogen bond is strongest in that molecules have a higher difference in electronegativity. Due to the small size of the oxygen atom, it has the highest electronegative character. So, \[\ce{H2O}\] molecules will have the strongest hydrogen bonding.
\[\ce{HCl, HI}\] and \[\ce{H2S}\] do not have hydrogen bonding between their atoms. So, \[\ce{H2O}\] will have the strongest hydrogen bonding.
