Question

[Co(NH₃)₄ (NO₂)₂] Cl exhibits
(a) linkage isomerism, ionization isomerism and geometrical isomerism
(b) ionization isomerism, geometrical isomerism and optical isomerism
(c) linkage isomerism, geometrical isomerism and optical isomerism
(d) linkage isomerism, ionization isomerism and optical isomerism

Answer 1

Acc. To me

a is correct

1 linkage

This complex contain NO2 which is ambidentate(two atoms make bond with central atom it may be N or O)

2 ionisation

In soln it give different ion. If ionisation sphere have Cl it give Cl ion if I.S. Have NO2 it give NO2 ion both are different ions.

3. Geometrical

Central atom linked with 6 (monodentate)Ligand so coordination no. Is 6. And it is Ma4b2 type complex that make geometrical isomerism.

I hope it help

Answer 2

Explanation:

organic compounds with same molecular formula but different chemical and physical properties are called isomers the phenomena is called ISO marriage the difference in properties of this compound is due to the difference in the inner structure this compound have identical molecular formula but different structures hence they are called structural isomerism and phenomena is called structural isomerism structural isomerism are possible for butane similarly in some compounds carbon atoms are arranged in the form of rain for example cyclohexene and benzene
