The type of isomerism exhibited by pentaamminenitrochromium (III) chloride is

• A

  Polymerization
• B

  Geometrical
• C

  Optical
• Correct answer
  D

  Linkage

Solution

Linkage isomerism arises in a coordination compound containing ambidentate ligand.



$\left[\text{C}\text{r}{\left(\text{N}{\text{H}}_3\right)}_5\text{N}{\text{O}}_2\right]\text{C}{\text{l}}_2\left(\text{l}\text{i}\text{n}\text{k}\text{a}\text{g}\text{e}\text{t}\text{h}\text{r}\text{o}\text{u}\text{g}\text{h}\text{N}\right)$

           and

$\left[\text{C}\text{r}{\left(\text{N}{\text{H}}_3\right)}_5\text{O}\text{N}\text{O}\right]\text{C}{\text{l}}_2\left(\text{l}\text{i}\text{n}\text{k}\text{a}\text{g}\text{e}\text{t}\text{h}\text{r}\text{o}\text{u}\text{g}\text{h}\text{O}\right)$

Hence, the correct answer is option: 'D'.
