Which is more polar and why, `CO_(2) or N_(2)O`?

Explanation

`N_(2) O ` is more polar than `CI_(2)` . This is because `CO_(2)` is linear and symmetrical . Its net dipole moment is zero
`(Ooverset(larr)=Coverset(rarr)(=O)) . N_(2) O` is linear but unsymmetrical . It is considered as a reasonance hybrid of the following
two structrure :
`:overset(-)overset(. .)N= overset(+)N= overset(. .)O: harr :N-=overset(+)N-overset(-)overset(. .)underset(. .)O:`
It has a net dipole moment of 0.116 D.
