Question

Explain that \([Co(NH_3)_5Cl]SO_4\) and \([Co(NH_3)_5SO_4]Cl\) are of which type of isomers.

Hint:

Linkage isomerism occurs when a ligand can bind to the metal through different atoms.

Answer 1

Step 1: Identify the Isomers
The given compounds are coordination compounds of cobalt. They have the same molecular formula but differ in the position of the ligands, so they are a type of **linkage isomers**.
Step 2: Explanation of Linkage Isomerism
In linkage isomerism, a ligand can coordinate to the metal center through different atoms. For example, in \([Co(NH_3)_5Cl]SO_4\), the chloride ion (\(Cl^-\)) is coordinating to the cobalt center, while in \([Co(NH_3)_5SO_4]Cl\), the sulfate ion (\(SO_4^{2-}\)) is coordinating. Final Answer: The compounds \([Co(NH_3)_5Cl]SO_4\) and \([Co(NH_3)_5SO_4]Cl\) are linkage isomers. Correct Answer: Linkage isomers.
