If the boiling point of H2O is 373 K, the boiling point of H2S will be :

At room temperature water is liquid and has high Boiling point 373K due to inter molecular hydrogen bonding where as H2S  is gas it has no hydrogen bonding. Hence is less than 300K. [BP if H2S is -60ºC] b.p. of H2 S≤H2ObpH2O=373 KbpH2 S=213 K
