If the boiling point of H 2 O is 373 K , and the boiling point of H 2 S will be :
Options
- Aless than 300   K
- Bequal to 373   K
- Cmore than 373   K
- Dgreater than 300   K but less than 373   K
Correct answer
A. less than 300   K
Step-by-step solution
At room temperature water is liquid and has boiling points 373   K due to hydrogen bonding. Where as H 2 S is gas and it has no hydrogen bonding. Hence boiling point of H 2 S is less than 300   K [Boiling point of H 2 S is - 60 ° C ]
