Chapter 22.5, Problem 22.3E

 (a)

Interpretation Introduction

Interpretation:

Geometric isomers of the following complexes has to be drawn.

(a) ${\left[Co{(N{H}_3)}_{5}Cl\right]}^{2+}$ (b) ${\left[Co{(N{H}_3)}_4{(H_{2}O)}_2\right]}^{3+}$

Concept Introduction:

A compound that has same molecular formula but different structural formula is said to exhibit isomerism.  Co-ordination compounds exhibit cis-trans isomerism which is a type of geometric isomerism.

A cis isomer has two same ligands lying adjacent to each other whereas a trans isomer has two same ligands lying opposite to each other.
