The C–C bond length is maximum in :
Show Hint
- C60
- diamond
- graphite
- C70
The Correct Option is B
Solution and Explanation
Graphite: sp2 with delocalised pi bonding, 141.5 pm.
C60: about 143.5 pm (single) and 138.3 pm (double); C70 has similar values (about 137-147 pm).
The longest C-C bond is in diamond.
Answer: (2) diamond

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:
