Co-Ordination Compounds Question 286

Question: Possible isomerism in complexes [Co(NH3)3(NO2)3] and [Co(NH3)5(NO2)]Cl2 , respectively are:

Options:

A) Linkage and optical

B) Geometrical and linkage

C) Optical and ionization

D) Linkage and geometrical

Show Answer

Answer:

Correct Answer: B

Solution:

[Co(NH3)3(NO2)3]Cl2 complex exhibits geometrical isomerism (G.I.) Geometrical isomers = 2 (1 cis + 1 trans) Optical isomers = 0 Space isomers = 2 [Co(NH3)5(NO2)]Cl2 complex shows linkage and ionization isomerism.
