Question

How many six membered rings are present in Buckminsterfullerene $\left(C_{60}\right)$

• A. $12$
• B. $20$
• C. $16$
• D. None of these

Answer 1

The correct option is B $20$

The $C_{60}$ molecule has a shape like a soccer ball and is called Buckminsterfullerene.
It contains $20$ six-membered rings and $12$ five-membered rings.
A six-membered ring is fused with either six or five membered rings.
Five membered rings are fused only with six membered rings.
All the carbon atoms are identical and undergo $s{p}^2$ hybridisation.
Each carbon atom in $C_{60}$ forms three sigma bonds with other three carbon atoms.
