WebThe buckminsterfullerene (C 60) was discovered in 1960 by Kroto et al. in honor of the famous architect Buckminster Fuller [42]. Fullerene structure consists of closed carbon cages made up of 12 pentagons and a few hexagons which increase with increasing size of the fullerene ([(2n/2)—10], n = number of carbon atoms) [43]. WebThe most important organic chemistry concepts. In organic compounds, C-C single bond is always a sigma bond. In the C=C double bond, the first bond is always a sigma bond, while the second is a pi bond. If a carbon atom is bonded to 2 other C-atoms, it must then have 2 H-atoms to complete its valency of 4 and attain a stable octet electronic ...
