Co-Ordination Compounds Question 286
Question: Possible isomerism in complexes $ [Co{{(NH_3)}_3}{{(NO_2)}_3}] $ and $ [Co{{(NH_3)}_5}(NO_2)]Cl_2 $ , 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{{( NH_3 )}_3}{{( NO_2 )}_3} ]Cl_2 $ complex exhibits geometrical isomerism (G.I.) Geometrical isomers = 2 (1 cis + 1 trans) Optical isomers = 0 Space isomers = 2 $ [Co{{(NH_3)}_5}(NO_2)]Cl_2 $ complex shows linkage and ionization isomerism.
