Q82 / 180 · AIIMS 2012 · Chemistry
Arrange the following gases in order of their critical temperature.
$\mathrm{NH}_3, \mathrm{H}_2 \mathrm{O}, \mathrm{CO}_2, \mathrm{O}_2$
- A$\mathrm{NH}_3>\mathrm{H}_2 \mathrm{O}>\mathrm{CO}_2>\mathrm{O}_2$
- B$\mathrm{O}_2>\mathrm{CO}_2>\mathrm{H}_2 \mathrm{O}>\mathrm{NH}_3$
- Correct answerC$\mathrm{H}_2 \mathrm{O}>\mathrm{NH}_3>\mathrm{CO}_2>\mathrm{O}_2$
- D$\mathrm{CO}_2>\mathrm{O}_2>\mathrm{H}_2 \mathrm{O}>\mathrm{NH}_3$
Solution
Greater are the intermolecular forces of attraction, higher is the critical temperature.
Hence, the correct answer is option: 'C'.
