# Why is a CO_2 molecule is nonpolar?

There is some, little degree of polarity, of charge separation, in the $C - O$ bonds...........
Neverthless, because the $C {O}_{2}$ molecule is LINEAR, the vector sum of the individual $C \rightarrow O$ dipoles cancels to ZERO. Polarity results from a vector sum that is non-zero, and as a result $C {O}_{2}$ is non-polar.
