Following statements are given about fullerene .Find the number of correct statements :
(a) Fullerenes are made by the heating of graphite in an electric arc in the presence of inert gases such as helium or argon.
(b) fullerenes are the purest form of carbon because they have smooth structure, having dangling bonds.
(c) $C_{80}$ fullerenes have 12, five membered ring: and 30-six membered rings.
(d) Fullerenes have aromatic character.
(e) In $C_{60}$ fullerenes six membered ring is fused with six or five but a five membered ring can only fuse with six membered rings.

(e) In $C_{60}$ fullerenes six membered ring is fused with six or five but a five membered ring can only fuse with six membered rings.

Accepted Answer

C60 (fullerene) has 20 carbon atom rings with six members and 12 with five members, and it resembles a soccer ball.Five membered rings are exclusively connected to six membered rings whereas six membered rings are fused with both six membered and five membered rings.Thus, statement is incorrect.
