  FULLERENES -
                             Fullerenesis another class of carbon allotropes.
               The first one to be identified wasC-60 which has carbon atoms arranged in the
               shape of a football. Since this lookedlike the geodesic dome designed by the US
               architect Buckminster Fuller, the moleculewas named fullerene.
































               Thusdiamond, graphite,fullerene and amorphous carbonhave very different
               physical properties even though their chemical properties are the same.
