Answer to Question #270385 in Inorganic Chemistry for Neha

Question

Using examples elaborate on the following isomerism Linkage coordination ionisation briefly differentiate between the reactivity of ncl3 and nf3

Answer 1

 Linkage isomerism.

The same ligand is bonded to central metal atom or ion through different atoms. The molecular formula of linkage isomers is same but they differ in linkage of the ligand to central metal atom. Yellow coloured $[Co(NH_3 ​)_5 ​NO_2 ​]Cl_2$  and red coloured $[Co(NH_3 ​)_5 ​ONO]Cl_2$ are linkage isomers.

   

Ionisation isomerism (ion-ion exchange isomerism).

There is exchange of ions inside and outside the coordination sphere. The molecular formula of ionisation isomers is same but different ions are produced in solution. $[Co(NH_3 ​)_5 ​SO_4 ​]Br$

 and $[Co(NH_3 ​)_5 ​Br]SO_4$ ​ are ionisation isomers.
