QJEEM02Che1b8: JEE Main 2002 Chemistry - Class 12 JEEM02Che1b8 Solution: The type isomerism present in nitropentammine chromium ( I I I…

The chemical formula of nitropentammine chromium $$\left(\mathrm{I}\mathrm{I}\mathrm{I}\right)$$ chloride is

$$\left[Cr{\left(N{H}_3\right)}_{5}N{O}_2\right]C{l}_2$$

It can exist in following two structures

$$\left[Cr{\left(N{H}_3\right)}_{5}N{O}_2\right]C{l}_2$$ and

nitropentammine chromium $$\left(\mathrm{I}\mathrm{I}\mathrm{I}\right)$$ chloride

$$\left[Cr{\left(N{H}_3\right)}_{5}ONO\right]C{l}_2$$

Nitropentammine chromium $$\left(\mathrm{I}\mathrm{I}\mathrm{I}\right)$$ chloride

Therefore the type of isomerism found in this compound is linkage isomerism as nitro group is linked through $$N$$ as $$-N{O}_2$$ or through $$O$$ as $$-ONO.$$
