Question

Which of the following pairs represent linkage
isomers?
(a) [Pd(P Ph₃ )₂ (NCS)₂ ] and
[Pd ( P Ph₃)₂ (SCN)₂ ]
(b) [Co(NH₃ )₅ NO₃ ] SO₄ and
[Co(NH₃ )₅ SO₄ ]NO₃
(c) [PtCl₂ (NH₃ )₄ ] Br₂ and [Pt Br₂ (NH₃ )₄ ] Cl₂
(d) [Cu(NH₃ )₄ ][Pt Cl₄ ] and [Pt(NH₃ )₄ ][CuCl₄ ]

Answer 1

(c)

Answer 2

(a) [Pd(P Ph₃ )₂ (N CS)₂ ] & [Pd ( P Ph₃)₂ (S CN)₂ ]

Explanation:

Linkage isomers are coordination compounds with the same composition. But the connectivity of metal to the lig-and is different. [Pd(P Ph₃ )₂ (N CS)₂ ] and  [Pd ( P Ph₃)₂ (S CN)₂ ] are linkage isomers.

Option A is the answer.
