4. bond angle
5. polarity of molecule

Answer 1

The Lewis structure of CO2 shows a carbon atom with two double bonds to two oxygen atoms. It has a linear shape, a 180-degree bond angle, and is nonpolar due to its symmetric geometry.

Step-by-step explanation:

To determine the Lewis structure and other properties of CO2, we'll go through several steps using the Valence Shell Electron Pair Repulsion (VSEPR) theory.

1. The Lewis structure of CO2 shows carbon in the center with two double bonds connecting it to two oxygen atoms, with no lone pairs on the carbon atom.
2. Using VSEPR theory, we determine that there are two regions of electron density around the carbon atom (each double bond counts as one region).
3. According to the number of electron density regions, the electron pair geometry is linear and so is the molecular shape.
4. The bond angle in a linear molecule is 180 degrees.
5. The polarity of CO2 is nonpolar because the molecule is symmetric and the dipoles from the two double bonds cancel each other out.

The VSEPR formula for CO2 is AX2 where 'A' represents the central atom and 'X' represents the surrounding atoms.
