Isomerism in Coordination Compounds Quiz

What are isomers?

• Compounds with the same chemical formula and same arrangement of atoms

• Compounds with the same chemical formula but different arrangement of atoms

• Compounds with different chemical formula and same arrangement of atoms

• Compounds with different chemical formula and different arrangement of atoms

Which type of isomerism arises in heteroleptic complexes due to different possible geometric arrangements of the ligands?

• Structural isomerism

• Linkage isomerism

• Coordination isomerism

• Stereoisomerism

Why is geometrical isomerism not possible in tetrahedral complexes having two different types of unidentate ligands coordinated with the central metal ion?

• The ligands are not attached to the central metal atom

• The relative positions of the ligands are the same with respect to each other

• The ligands are not geometrically arranged

• The ligands are not isomers

What is the term for isomerism that arises from the interchange of ligands between cationic and anionic entities of different metal ions present in a complex?

• Ionisation isomerism

• Solvate isomerism

• Linkage isomerism

• Coordination isomerism

In which type of isomerism do solvate isomers differ by whether or not a solvent molecule is directly bonded to the metal ion?

• Coordination isomerism

• Solvate isomerism

• Linkage isomerism

• Ionisation isomerism

Which type of isomerism occurs in octahedral coordination entities involving didentate ligands?

• Geometrical isomerism

• Linkage isomerism

• Structural isomerism

• Optical isomerism

What is the term for the two forms of optical isomers that rotate the plane of polarised light in opposite directions?

• Facial and Meridional

• Both are non-chiral

• (b) trans-[CrCl2 (ox)2]3–

• Both are chiral

• (a) cis-[CrCl2 (ox)2]3–
