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.

Answer:

                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.
