CO2 - Carbon Dioxide:

First draw the lewis structure of CO2, Carbon dioxide:
CO2 Lewis Structure
Electron geometry: linear. Hybridization: sp

Then draw the 3D structure with VSEPR rules:

The molecular geometry of CO2 is linear with symmetric charge distribution about the carbon atom.
Therefore CO2 is non-polar.
