Polarity and Bonding in CO2

The video explores whether carbon dioxide (CO2) is ionic or covalent. It explains that CO2 is a covalent compound because it consists of two non-metals, carbon and oxygen. The Lewis structure of CO2 is shown, highlighting the sharing of electrons between carbon and oxygen, forming covalent bonds. The video also discusses the polarity of CO2, noting that despite the polar covalent bonds, the molecule is non-polar due to its symmetrical shape, which cancels out the dipoles.
