The structure of \(\mathrm{PCl_5}\) in the solid state is :
Show Hint
- square pyramidal
- tetrahedral \(\mathrm{[PCl_4]^+}\) and octahedral \(\mathrm{[PCl_6]^-}\)
- square planar \(\mathrm{[PCl_4]^+}\) and octahedral \(\mathrm{[PCl_6]^-}\)
- trigonal bipyramidal
The Correct Option is B
Solution and Explanation
\(\mathrm{[PCl_4]^+}\): 4 bond pairs, no lone pair, sp3, tetrahedral.
\(\mathrm{[PCl_6]^-}\): 6 bond pairs, sp3d2, octahedral.
Therefore the correct description is tetrahedral cation and octahedral anion.
Answer: (2) tetrahedral \(\mathrm{[PCl_4]^+}\) and octahedral \(\mathrm{[PCl_6]^-}\)

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:
