Question
Which is more polar: CO2 or N2O? Give reason.
✓

Answer

N2O is more polar than CO2. This is because CO2 is linear and symmetrical. Its net dipole moment is zero,

N2O on the other hand, is linear but unsymmetrical. It is considered as a resonance hybrid of the following two structures.

It has a net dipole moment of 0.116D.
