\(\mathrm{[Co_2(CO)_8]}\) displays :
Show Hint
- one Co-Co bond, six terminal CO and two bridging CO
- one Co-Co bond, four terminal CO and four bridging CO
- no Co-Co bond, six terminal CO and two bridging CO
- no Co-Co bond, four terminal CO and four bridging CO
The Correct Option is A
Solution and Explanation
In the bridged structure each Co has 3 terminal CO (6 e), 2 bridging CO (1 e each from the two bridges, 2 e) and one Co-Co bond (1 e): \(9 + 6 + 2 + 1 = 18\).
Total CO: \(2\times3 = 6\) terminal and 2 bridging = 8.
Answer: (1) one Co-Co bond, six terminal CO and two bridging CO

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:
