Why Functional Groups attached to Graphene Oxide ?

Carboxylic (-COOH) groups are mainly located at the edges of the GO
Hydroxyl (-OH) & epoxy (C-O-C) groups attached to the basal plane of GO.
During the oxidation reaction, different oxygen functional groups attached. For instance, hydroxyl groups (-OH) and epoxide (C-O-C) are randomly distributed on the basal surface and carboxylic group(C=O and -COOH), at edges.

Thank you very much, this video is educative.

You are always welcome

Thank you sir

Sir graphene reacts with which functional group and after reaction graphene will be a conductor

[@qamarwali]

Due to these functional groups, graphene becomes reactive and can be easily dissolved in the solvent like water or DMF, etc.

Is GO crystalline or amorphous?

[@qamarwali]

GO is crystalline for sure. As the carbon atoms distributed in a hexagonal pattern in GO structure. So there are periodicity in the atomic order....
If you wish to make it sure. Just take the XRD of GO, it will give sharp peaks.
*Crystalline materials* give *sharp peaks* in XRD pattern
*Amorphous materials* give * broad peaks* in XRD pattern

Sir graphene dissolved in which solvent during uv vis spectroscopy
Sir I used a ethanol but my graphene is not dissolved in it kindly guide me which solvent use for graphene in uv vis spectroscopy

[@ahmadkaki604]

Many thanks for your informative explanation... I do have one question... You have mentioned that reduced GO is polar, so it can dissolve in water... My question is that I am dealing with GO MOF (UiO-66-NH22) and it is difficult to be dissolved in water... Hope you can clear the picture for me

[@qamarwali]

It does not mean that GO will only dissolve in water. There are so many other polar solvents like DMF, acetone, acetonitrile, DMSO... Just try with other solvent.
I strong recommend read the relevant literature to your sample
You are always welcome
