Chapter 22, Problem 22.54QP

(a)

Interpretation Introduction

Interpretation:

Structure of cis-trans isomer of the following complexes has to be drawn.

(a) ${\left[Co{(N{O}_2)}_4{(N{H}_3)}_2\right]}^{-}$ (b) ${\left[Co{(N{H}_3)}_5{(NO)}_2\right]}^{2+}$ (c) ${\left[Co{(N{H}_3)}_6\right]}^{3+}$ (d) ${\left[Cr{(N{H}_3)}_{5}Cl\right]}^{2+}$

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.

(b)

Interpretation Introduction

Interpretation:

Structure of cis-trans isomer of the following complexes has to be drawn.

(a) ${\left[Co{(N{O}_2)}_4{(N{H}_3)}_2\right]}^{-}$ (b) ${\left[Co{(N{H}_3)}_5{(NO)}_2\right]}^{2+}$ (c) ${\left[Co{(N{H}_3)}_6\right]}^{3+}$ (d) ${\left[Cr{(N{H}_3)}_{5}Cl\right]}^{2+}$
