Chiral complex from the following is
Chiral complex from the following is
Show Hint
For identifying chiral complexes:
• Check for the absence of planes of symmetry or center of symmetry.
• Cis configurations with bidentate ligands (like en) often result in chiral complexes.
• Trans configurations are usually symmetric and achiral.
trans – [Co(NH3)4Cl2] +
cis – [PtCl2(en)2] 2+
cis – [PtCl2(NH3)2]
trans – [PtCl2(en)2] 2+
The Correct Option is B
Solution and Explanation
Chirality in coordination complexes occurs when the complex lacks a plane of symmetry.
- For the given complexes:
cis–[PtCl\(_2\)(en)\(_2\)]\(^{2+}\): The cis arrangement of ethylene diamine (en) ligands around the Pt center creates a chiral structure.
trans–[PtCl\(_2\)(en)\(_2\)]\(^{2+}\): The trans arrangement is symmetric, making the complex achiral.
cis–[PtCl\(_2\)(NH\(_3\))\(_2\)]: The complex has a plane of symmetry and is not chiral.
trans–[Co(NH\(_3\))\(_4\)Cl\(_2\)]\(^+\): The trans arrangement of ligands makes the complex symmetric and achiral.
Final Answer: (1) cis–[PtCl\(_2\)(en)\(_2\)]\(^{2+}\).

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:
