Which is more polar \[-C{{O}_{2}}\] or \[{{N}_{2}}O\]? Give reason.

Answer:

                \[{{N}_{2}}O\] is more polar than \[C{{O}_{2}}\]. This is because \[C{{O}_{2}}\] is linear and symmetrical. Its net dipole moment is zero \[(O\overset{\leftarrow }{\mathop{=}}\,C\overset{\to }{\mathop{=}}\,O).\]\[{{N}_{2}}O\]  is linear but unsymmetrical. It is considered as a resonance hybrid of the following two structures: It has a net dipole moment of 0.116 D.
