Question

Choose the correct option(s):
Here
a,b are monodentate ligands
AB is an unsymmetrical bidentate ligand

• A. $Co(gly{)}_3$ does not have any geometrical isomers.
• B. $Co(gly{)}_3$ has 4 geometrical isomers.
• C. $\left[M\right(AB{)}_2{a}_2{b}_2{]}^{n\pm }$ has 4 geometrical isomers.
• D. None of the above

Answer 1

The correct option is C $\left[M\right(AB{)}_2{a}_2{b}_2{]}^{n\pm }$ has 4 geometrical isomers.

Unsymmetrical Bidentate and Monodentate Ligands
$\left[M\right(AB{)}_2{a}_2{b}_2{]}^{n\pm }$ has 4 geometrical isomers as shown:
$Co(gly{)}_3$ has 2 geometrical isomers as shown:
Option (c) is correct.
