Chapter 19, Problem 43E

Interpretation Introduction

Interpretation: The optically activeisomers in the given complexes needs to be determined.

  ${\text{cis-Cr(acac)}}_{\text{2}}{{\text{(H}}_{\text{2}}\text{O)}}_{\text{2}}$ , ${\text{trans-Cr(acac)}}_{\text{2}}{{\text{(H}}_{\text{2}}\text{O)}}_{\text{2}}$ , ${\text{Cr(acac)}}_3$

Concept Introduction:

A metal complex can be show as ${\text{[ML}}_{\text{n}}\text{]}$ . Here M indicates the metal atom or ion whereas L indicates the ligands which are present in ‘n’ numbers. The coordination number defined the number of coordinate bonds between metal and ligand.

Stereoisomer can be defined as the coordination complexes or molecules which have same structural formula but different arrangement of bonded atoms or group in 3-D space.

Optical isomers can be defined as the complexes or molecules which have same structural formula but different orientation of bonded ligands in the plane therefore they show different optical properties.
