Type of isomerism which exists between [Pd(C6H5)2(SCN)2] and [Pd(C6H5)...
**Answer:**
The type of isomerism that exists between [Pd(C6H5)2(SCN)2] and [Pd(C6H5)2(NCS)2] is **linkage isomerism**.
**Explanation:**
Linkage isomerism is a type of coordination isomerism in which the ligands are attached to the central metal ion through different atoms. In this case, the ligands are thiocyanate (SCN-) and isothiocyanate (NCS-), which are isomers of each other.
In [Pd(C6H5)2(SCN)2], the thiocyanate ligands are coordinated to the palladium ion through the sulfur atom. On the other hand, in [Pd(C6H5)2(NCS)2], the isothiocyanate ligands are coordinated to the palladium ion through the nitrogen atom.
The difference in coordination atoms leads to different chemical and physical properties of the isomers. The isothiocyanate ligands (NCS-) are generally more labile than the thiocyanate ligands (SCN-), meaning they can be easily replaced by other ligands. This difference in reactivity can have important implications in various chemical reactions and processes.
Therefore, the existence of two isomers with different ligands attached through different atoms is an example of linkage isomerism. The isomers have the same chemical formula but differ in the arrangement of the ligands around the central metal ion, resulting in different properties and behaviors.
In conclusion, the correct answer is option **A) Linkage isomerism**.
Type of isomerism which exists between [Pd(C6H5)2(SCN)2] and [Pd(C6H5)...
Linkage isomerism because central metal atom is attached with ambident ligand which consists of two donor atoms like NCS
