Question

What are the properties of carbon that gives to the formation of fullerenes. Name two other compounds which are allotropes. In which of these compounds all the four valencies are satisfied?

Answer 1

Fullerene are cystalline cage like spheroidal molecules with general formula of C2n (n>=30) e.g.C60, C70, C60 etc.look likes soccer ball containing 20six membered rings and 12 five numbered rings .five membered rings are only attached six membered rings whereas six membered rings are attached to both six membered rings .

diamonds and coke are other two allotropes of carbon which satisfy all four vacancy.
