Question

$\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_4{\mathrm{Cl}}_2\right]{\mathrm{NO}}_2$ and $\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_4\mathrm{Cl}\right({\mathrm{NO}}_2\left)\right]\mathrm{Cl}$ exhibit which type of isomerism?

Answer 1

Isomerism:

• Having the same chemical formula but different structural properties, Iwo or more compounds Isomerism is a process that produces formulas known as isomers.

Ionization isomerism:

• Ionization isomerism refers to compounds that produce distinct ions in solution despite having the same chemical makeup.
• This type of isomerism occurs when the counter ion in a complex salt may displace a ligand, which can then turn into the counter ion, by becoming a potential ligand itself.
• Except for a ligand that has switched places with an anion or neutral molecule that was previously outside the coordination complex, ionization isomers are indistinguishable.
• Thus, $\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_4{\mathrm{Cl}}_2\right]{\mathrm{NO}}_2$ and $\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_4\mathrm{Cl}\right({\mathrm{NO}}_2\left)\right]\mathrm{Cl}$ are examples of ionization isomers.

$\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_4{\mathrm{Cl}}_2\right]{\mathrm{NO}}_2$ and $\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_4\mathrm{Cl}\right({\mathrm{NO}}_2\left)\right]\mathrm{Cl}$ exhibit ionization isomerism.
