Coordination Compounds - Result Question 1
####1. The type of isomerism shown by the complex $[CoCl_2(en)_2]$ is
[2018]
(a) Geometrical isomerism
(b) Coordination isomerism
(c) Linkage isomerism
(d) Ionization isomerism
Show Answer
Solution:
(b) $[Co(NH_3)_6] Cl_3 \xrightarrow{AgNO_3}$
$[Co(NH_3)_5 Cl] Cl_2 \xrightarrow{AgNO_3}$
$2 mol$ of $AgCl$
$[Co(NH_3)_4 Cl_2] Cl \xrightarrow{AgNO_3} 1 mol$ of $AgCl$
Complexes are respectively $[Co(NH_3)_6] Cl_3$, $[Co(NH_3)_5 Cl] Cl_2$ and $[Co(NH_3)_4 Cl _2] Cl$
