Arrange the following gases in order of their critical temperature. NH ₃, H ₂ O , CO ₂, O ₂

Options

  1. ANH ₃> H ₂ O > CO ₂> O ₂
  2. BO ₂> CO ₂> H ₂ O > NH ₃
  3. CH ₂ O > NH ₃> CO ₂> O ₂
  4. DCO ₂> O ₂> H ₂ O > NH ₃

Correct answer

C. H ₂ O > NH ₃> CO ₂> O ₂

Step-by-step solution

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