Allotropes of carbon: There are three forms of carbon. i.e., diamond, graphite and fullerene which exxist in crystalline form. Graphite and diamond occur in nature. The structure of diamond is tetrahedral with `sp^(3)` hybridisation and diamond exist in 3-D netowrk solid. in graphite, carbon is `sp^(2)` hybridised. each carbon linked to other carbon linked to other carbon atom forms hexagonal ring. it has a layered structure. diamond and graphite are purest form of carbon. Fullerene constitute a new family of carbon allotropes.
Consisting of large spheroidal molecule of compound with general formula `C_(2n)`. common fullerene `C_(6),C_(70)`, contain 5 and 6 membered rings.
Q. Which of the following statement is incorrect for graphite?
