CO2, or carbon dioxide, is a linear molecule. Here's a description of its structure:

* Central Carbon Atom: A single carbon atom sits at the center of the molecule.

* Oxygen Atoms: Two oxygen atoms are positioned on either side of the carbon atom.

* Bonding: The carbon atom is double-bonded to each oxygen atom.

Visual Representation:

You can imagine CO2 like this:

* O = C = O

Key Points:

* Linear Shape: The molecule is straight, with the carbon atom in the middle and the oxygen atoms at opposite ends.

* Double Bonds: The strong double bonds between carbon and oxygen are responsible for CO2's stability.

* Polarity: Despite the presence of oxygen (a highly electronegative element), CO2 is a nonpolar molecule due to its symmetrical shape and the cancellation of dipole moments.

Additional Note:

Because of its shape, CO2 cannot form hydrogen bonds.
