\(Cu ( II )\) के अष्टफलकीय संकुल संरचनात्मक विकृति (जान-टेलर) प्रदर्शित करते हैं। दिए गए \(Cu (II)\) संकुलों में कौनसा अधिकतम संरचनात्मक विकृति प्रदर्शित करेगा ?\((en-\)एथिलीनडाइऐमीन; \(H _2 N - CH _2- CH _2- NH _2\) )

  1. A \([ Cu ( H _{2} O )_{6}] SO _{4}\)
  2. B \([ Cu ( en )( H _{2} O )_{4}] SO _{4}\)
  3. C cis- \([ Cu ( en )_{2} Cl _{2}]\)
  4. D trans- \([ Cu ( en )_{2} Cl _{2}]\)
Verified Solution

Answer & Solution

Correct Answer

(A) \([ Cu ( H _{2} O )_{6}] SO _{4}\)

Step-by-step Solution

Detailed explanation

There is unsymmetric filling of \(e_{g}\) subset of \(Cu ^{+2} \;ion\), while there is symmetrical distribution in \(t _{2 g }\) set, if the complex has same ligand there will be equal repulsion which leads to symmetrical bond length along \(t _{2 g }\) , but due to uneven…
