Graphite Bonding Structure Asbury Carbons

The sp2 carbon atom is very important in terms of graphite because graphite is made up of almost pure sp2-type carbon atoms. The significance of sp2 carbon and graphite will be covered in more detail later. The concept of aromaticity and resonance as it relates to sp2 hybridization will be covered in another section of this site.
