JEE PYQ: P Block Elements Question 23
Question 23 - 2020 (03 Sep Shift 1)
If the boiling point of $\text{H}_2\text{O}$ is 373 K, the boiling point of $\text{H}_2\text{S}$ will be:
(1) less than 300 K
(2) equal to 373 K
(3) more than 373 K
(4) greater than 300 K but less than 373 K
Show Answer
Answer: (1)
Solution
At room temperature, water is liquid and has boiling point 373 K due to hydrogen bonding. Whereas $\text{H}_2\text{S}$ is a gas and it has no hydrogen bonding. Hence boiling point of $\text{H}_2\text{S}$ is less than 300 K (boiling point of $\text{H}_2\text{S}$ is $-60^\circ$C).
