VSEPR Geometry and Polar/Non-Polar Molecules

CO₂ has polar bonds but is a NON POLAR molecule. Why?

• it has an asymmetrical shape

• bond polarity or dipole moment between C and O atoms cancel

• there is net dipole moment between C and O atoms in molecule

• bond polarity does not exist between C⁺ and O^- atoms

Does the following reference Polar, Nonpolar, or both:

"electronegativity values are the same"?

• Polar

• Nonpolar

• Both

Is this molecule polar or nonpolar?

• polar

• nonpolar
