Although graphite is thermodynamically most stable allotrope of Carbon but it has more entropy than diamond Because:

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 correct regarding C_(60) fullerene?
