Diamond, graphite and graphene are forms of carbon with different giant covalent structures. Part of. WebIn chemistry, pi stacking (also called π–π stacking) refers to the presumptive attractive, noncovalent pi interactions ( orbital overlap) between the pi bonds of aromatic rings. However this is a misleading description of the phenomena since direct stacking of aromatic rings (the "sandwich interaction") is electrostatically repulsive. citizens bank woburn ma

http://butane.chem.uiuc.edu/pshapley/GenChem2/A6/3.html WebThe Pi (π) bonds are formed by sidewise overlap of half-filled atomic orbitals of atoms taking part in bonding. Note that sigma bonds are stronger than Pi bonds. For graphite, two 2p and one 2s orbitals hybridize to form sp 2 atomic orbitals at a lower energy level, while a single p orbital remains at the original 2p energy level.
