# Why is carbon dioxide a non-polar molecule?

Jan 8, 2016

Molecular polarity arises from the vector sum of the individual bond-dipoles.

#### Explanation:

For each $C = O$ bond we could draw a vector representing bond polarity $\rightarrow$, where the arrow points to the negative end. Because carbon dioxide is linear, these dipoles sum up to zero, and the carbon dioxide molecule is non-polar.
