Arrange the following gases in order of their critical temperature. NH3,H2O,CO2,O2\mathrm{NH}_3, \mathrm{H}_2 \mathrm{O}, \mathrm{CO}_2, \mathrm{O}_2

Options

  1. ANH3>H2O>CO2>O2\mathrm{NH}_3>\mathrm{H}_2 \mathrm{O}>\mathrm{CO}_2>\mathrm{O}_2
  2. BO2>CO2>H2O>NH3\mathrm{O}_2>\mathrm{CO}_2>\mathrm{H}_2 \mathrm{O}>\mathrm{NH}_3
  3. CH2O>NH3>CO2>O2\mathrm{H}_2 \mathrm{O}>\mathrm{NH}_3>\mathrm{CO}_2>\mathrm{O}_2
  4. DCO2>O2>H2O>NH3\mathrm{CO}_2>\mathrm{O}_2>\mathrm{H}_2 \mathrm{O}>\mathrm{NH}_3

Correct answer

C. H2O>NH3>CO2>O2\mathrm{H}_2 \mathrm{O}>\mathrm{NH}_3>\mathrm{CO}_2>\mathrm{O}_2

Step-by-step solution

Greater are the intermolecular forces of attraction, higher is the critical temperature.
