why does CO2 show large deviation than H2,N2 etc from ideal gas?

CO₂ molecule is quite large as compared to H₂ and N₂. The particles in CO₂ will be closer to each other. So, there will be stronger van der waals attractions between the molecules of CO₂ as compared to H₂ and N₂ which are small in size. ​​ More the interactions, more will be the deviation from ideal behaviour. Thus CO₂ will show larger deviation.
