Which hydride has the highest boiling point among $H X_{2} O$ , $H X_{2} S$ , $H X_{2} Se$ and $H X_{2} Te$ at 1 atm?

A $H X_{2} S$
B $H X_{2} Se$
C $H X_{2} Te$
D $H X_{2} O$

Answer: D

Water molecules are strongly associated through hydrogen bonding because oxygen is small and highly electronegative. This raises its boiling point far above those of the heavier hydrides (about 373 K versus roughly 213 to 271 K for the others).
