What is Introduction to Isomerism?

The phenomenon where two or more compounds have the same molecular formula but differ in the arrangement of atoms or groups, leading to different physical or chemical properties.

Key points

  • Define isomerism in the context of coordination compounds.
  • Differentiate between stereoisomers and structural isomers.
  • Recognize the significance of isomerism in coordination chemistry.

Common exam trap

Confusing isomerism with allotropy or polymorphism.

Definitions

Term

Isomerism

Meaning

The phenomenon where two or more compounds have the same molecular formula but differ in the arrangement of atoms or groups, leading to different physical or chemical properties.

Term

Coordination Compound

Meaning

A compound containing a central metal atom or ion bonded to a surrounding array of ligands, typically through coordinate covalent bonds.

Term

Ligand

Meaning

An ion or molecule that binds to a central metal atom to form a coordination complex.
