Question

The incorrect statement regarding the structure of $C_{60}$ is

• A. It contains 12 six-membered rings and 24 five-membered rings
• B. The six-membered rings are fused to both six and five-membered rings
• C. Each carbon atom forms three sigma bonds
• D. The five-membered rings are fused only to six-membered rings

Answer 1

The correct option is A It contains 12 six-membered rings and 24 five-membered rings

$C_{60}$ contains twenty six-membered rings and twelve five-membered rings.


$C_{60}$ (fullerene) looks like a soccer ball and contains 20 six membered rings and 12 five membered rings of carbon atoms.

Six membered rings are fused with both six membered as well as five membered rings while five membered rings are attached only with six membered rings.
