• # question_answer Gases like $C{{O}_{2}}$ and $C{{H}_{4}}$ show more deviation from the ideal gas behaviour as compared to gases like ${{H}_{2}}$  and He. Explain.

In $C{{O}_{2}}$ and$C{{H}_{4}}$, the molecular size is more as compared to ${{H}_{2}}$ and He. Therefore, if we neglect the molecular volume in these gases in the same way as we do for ${{H}_{2}}$ and He, the deviations from the ideal gas behaviour are likely to be more.
