Question
Discuss the structure and properties of fullerene $(C6o).$
✓
Answer
$C_{60}$ has a shape like soccer ball and called Buckminsterfullerene or bucky ball.
It contains $20$ hexagonal and $12$ pentagonal fused rings of carbon.
The $C_{60}$ fullerene structure exhibit separations between the neighbouring carbons as $143.5 \ pm$ and $138.3 \ pm.$
Fullerenes are covalent and soluble in organic solvents.
Fullerene $C_{60}$ reacts with group $1$ metals forming solids such as $K_3C_{60}.$
The compound $K_3C_{60}$ behaves as a superconductor below $18 K,$ which means that its carries electric current with zero resistance.
