Show Hint
- (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
- (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)
- (a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)
- (a)-(iv), (b)-(ii), (c)-(iii), (d)-(i)
The Correct Option is B
Solution and Explanation
(b) [Co(NH3)3(NO2)3] contains the ambidentate NO2- ligand (binds through N or O): linkage isomerism (i).
(c) [Cr(H2O)6]Cl3 can exchange water inside and outside the coordination sphere, e.g. [Cr(H2O)5Cl]Cl2·H2O: solvate (hydrate) isomerism (ii).
(d) cis-[CrCl2(ox)2]3- has no plane of symmetry and exists as non-superimposable mirror images: optical isomerism (iv).
So (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv).
Answer: (2) (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)

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:
