FAQs on Short Tricks: Geometrical & Optical Isomerism in Coordination Compounds

Question 1

1. What is geometrical isomerism in coordination compounds?

Accepted Answer

Ans. Geometrical isomerism in coordination compounds refers to the phenomenon where the ligands around a central metal ion can be arranged in different spatial orientations, resulting in isomers with different geometrical structures.

Question 2

2. What is optical isomerism in coordination compounds?

Accepted Answer

Ans. Optical isomerism in coordination compounds occurs when a compound has a non-superimposable mirror image. This means that the compound can exist in two forms, known as enantiomers, which are mirror images of each other but cannot be overlapped onto each other.

Question 3

3. How can we determine the presence of geometrical isomerism in coordination compounds?

Accepted Answer

Ans. Geometrical isomerism can be determined by examining the coordination sphere of a complex. If the complex has different ligands arranged in a specific way, such as in a square planar or octahedral geometry, then geometrical isomerism may be present.

Question 4

4. What factors contribute to the formation of geometrical isomers in coordination compounds?

Accepted Answer

Ans. The formation of geometrical isomers depends on several factors, including the nature of ligands, the coordination number of the metal ion, and the spatial arrangement of ligands around the metal ion. For example, ligands with different sizes or shapes can lead to the formation of geometrical isomers.

Question 5

5. How does optical isomerism affect the properties of coordination compounds?

Accepted Answer

Ans. Optical isomerism can significantly impact the properties of coordination compounds. Enantiomers of a compound often exhibit different physical, chemical, and biological properties. This is because enantiomers interact differently with other molecules due to their distinct three-dimensional arrangements, leading to variations in their behavior and reactivity.
