Vedclass · Answer

(D) The structure of $C_{60}$ (Buckminsterfullerene) consists of $60$ carbon atoms arranged in a truncated icosahedron shape.It contains $20$ six-membered rings (hexagons) and $12$ five-membered rings (pentagons).Each carbon atom is $sp^2$ hybridized and forms three sigma bonds.The five-membered rings are fused only to six-membered rings,while the six-membered rings are fused to both six and five-membered rings.Therefore,the statement that it contains $12$ six-membered rings and $24$ five-membered rings is incorrect.

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