Chapter 20, Problem 5RQ

Interpretation Introduction

Interpretation: The concept of absence of optical inactivity for a complex on the basis of presence of plane of symmetry is given. The definition of the given terms, the optical behavior of $\left[\text{Cr}{\left(\text{en}\right)}_2{\text{Cl}}_2\right]$ and the presence of plane of symmetry in trans isomer and its absence in cis isomer is to be stated.

Concept introduction: The transition metal atoms have a tendency to form complex compounds that are linked to the certain neutral or ionic species and this leads to the formation of coordination compounds. There exists a large number of coordination compounds that have a large number of applications in the chemical industry as well as in daily life.
