Graphitic acid-Its structure and properties?
Graphitic acid is a compound derived from graphite.

You may find it named "Graphite oxide" as well: as you see, it is obtained by reacting graphite with an oxidizing agent ($\ce{HNO3}$, for instance).

The structure resembles that of graphite, but it carries several oxygen-containing substituents, such as hydroxyl and carbonyl functions, thus having a less regular geometry, compared to that of graphite.

The exact features of the structure depend a lot on the method used for its preparation, and the layers may show some "defects", not described by this ideally planar model, but the key concept is this.

Here is a simple proposed structure for a single layer (source: Wikipedia)



Note that, just like graphite is made of several layers of graphene, graphite oxide is made of several layers that, upon reaction with a base, become graphene oxide.
