How to Draw the Lewis Structure of CO2

TL;DR

To draw the Lewis structure of carbon dioxide (CO2), add the valence electrons: carbon has 4 and each oxygen has 6, totaling 16. Carbon forms four bonds with two double bonds to the oxygens, each having two lone pairs. The resulting structure has a linear shape with a bond angle of 180 degrees and hybridization of the central carbon as sp.

Questions & Answers

Q: How can you determine the number of valence electrons for carbon and oxygen?

Carbon is in group 4A of the periodic table, so it has four valence electrons. Oxygen is in group 6A, meaning it has six valence electrons.

Q: Why does oxygen form two bonds?

Oxygen wants to have eight electrons in its outermost shell, so it forms two bonds to acquire the two extra electrons it needs.

Q: What is the molecular shape of carbon dioxide?

Carbon dioxide has a linear molecular shape, resembling a straight line.

Q: What is the bond angle in carbon dioxide?

The bond angle in carbon dioxide is 180 degrees, forming a straight line between the oxygen atoms and the central carbon atom.

Summary & Key Takeaways

• Carbon dioxide's Lewis structure is formed by adding up the valence electrons of carbon and the two oxygen atoms in the molecule.

• Carbon has four valence electrons, while oxygen has six. Since there are two oxygen atoms, the total number of valence electrons is 16.

• The Lewis structure shows carbon forming four bonds, each oxygen forming two bonds, and oxygen acquiring two lone pairs.
