The INCORRECT statement regarding the structure of \(\mathrm{C_{60}}\) is :
Show Hint
- The five-membered rings are fused only to six-membered rings.
- It contains 12 six-membered rings and 24 five-membered rings.
- Each carbon atom forms three sigma bonds.
- The six-membered rings are fused to both six and five-membered rings.
The Correct Option is B
Solution and Explanation
Each pentagon is surrounded by hexagons only, so the five-membered rings are fused only to six-membered rings (statement 1 correct).
Each hexagon is fused to three hexagons and three pentagons, so statement 4 is correct.
Every carbon is bonded to three other carbons by sigma bonds (plus one pi bond delocalised), so statement 3 is correct.
Statement 2, "12 six-membered and 24 five-membered rings", is wrong.
Answer: (2) It contains 12 six-membered rings and 24 five-membered rings.

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
