Carbon shows allotropic forms like Diamond, graphite, and Buckminsterfullerene. • 1. Diamond has a three-dimensional structure. • 2. Each carbon atom is bonded to four other carbon atoms, which occupy four corners of a tetrahedron and each of these carbon four carbon atoms is bonded to four more carbon atoms. • 3. Such a pattern is repeated in the entire crystal atoms. • Graphite • 1. Graphite has a two-dimensional sheet-like structure and the sheets may be considered as a fused system of planar hexagonal rings. • 2. In the planar hexagonal rings, each carbon atom is bonded to three other carbon atom. • FULLERENES • 1. Fullerene is a newly discovered allotrope of carbon which contain a soccer-ball-shaped cluster of carbon atoms C 60 • Fullerenes are cage-like molecules. C 6 • • 0 molecules have a shape like a soccer ball and called Buckminsterfullerene. It contains 20 six-membered rings is fused with a six or five-membered ring. All the carbon atoms are sp 2 hybridized. • 1. Buckminster Fullerene is one type of fullerene. Fullerenes are made from carbon atoms joined together to make balls, cages or tubes of carbon. The molecules of Buckminster Fullerene are spherical and are also known as 'buckyballs' formula C60. • Buckminster Fullerene is a black solid although it's deep red when in solution in petrol. The tube fullerenes are called nanotubes which are very strong. • 2. Diamond is another allotropic form of carbon in which carbon is tetrahedrally arranged and it is shiny, lustrous, and nonconductor of heat and electricity. • 3. Graphite is an allotrope of carbon in which carbon atoms are hexagon-ally placed to form a network structure. It is blackish, slippery and conductor of heat and electricity. • #carbon #allotropyofcarbon #allotropy • • For more videos, online classes, 24X7 Doubts solving and Mock tests, Visit Toppr - The better learning app. • #BetterLearning on the Toppr app, download now • Google Play: http://bit.ly/2vRBqcb • App Store: http://apple.co/2vpRAr9 • Website: https://www.toppr.com/ • Download Doubts on Chat App: • Android Play Store: http://bit.ly/2B6w7oy • iOS App Store: http://apple.co/2ziAA75 • Facebook: / beingtoppr • Twitter: / mytoppr • Instagram: / mytoppr • LinkedIn: / toppr-com
