JEE Main 2020 (03 Sep Shift 1)

Question

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

Choose an option

Show full solutionCorrect option: A
Correct answer
Aless than 300 K

Step-by-step explanation

At room temperature water is liquid and has boiling points 373 K due to hydrogen bonding. Where as H2S is gas and it has no hydrogen bonding. Hence boiling point of H2S is less than 300 K [Boiling point of H2S is -60 °C]
