Which statement is $NOT$ correct about fullerene $C_{60}$ ?

• A. It contains $20$ six membered rings and $12$ five membered rings
• B. All carbon atoms undergo $SP^{2}$ hybridization
• C. A six membered ring is fused with six membered rings only
• D. A five membered ring is fused with six membered ring only

Answer 1

Answer: (C)

$C _{60}$ (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.
