WebAug 14, 2024 · The coordination number of 3 reflects the sp 2-hybridization of carbon in graphite, resulting in plane-trigonal bonding and thus the sheet structure. Adjacent sheets are bound by weak dispersion forces, allowing the sheets to slip over one another and giving rise to the lubricating and flaking properties of graphite. WebGraphite is the crystalline allotropic form of carbon occurs in free state in nature. It can be prepared artificially by heating a mixture of sand and coke in electrical furnace at about 3300 K. In graphite, the carbon atoms …

WebGraphite. Again the carbon atoms are bonded together to make a giant structure but in this case all of the carbons are bonded to only three neighbour and are sp 2 hybridised. As the sp 2 hybridisation results in planar structures, there are giant 2 dimensional layers of carbon atoms and each layer is only weakly linked to the next layer by Van der Waal's forces.
