Fullerenes constitute a family of crystalline allotropes of carbon consisting of spherical or ellipsoidal molecules of composition `C_(2n)` when `n` is ` gt =` ____.

A

`20`

B

`30`

C

`40`

D

`15`

Text Solution

Verified by Experts

The correct Answer is:
B
Fullerenes were first prepared by the evaporation of graphite using a powerful laser. The sooty material formed by the condensation of vaporized graphite consists of `C_(2n)` molecules.

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?
