Verified step by step guidance1
Understand the concept of coordination isomers: Coordination isomers are a type of isomerism found in coordination compounds where the ligands and counterions exchange places between the coordination sphere and the outer sphere.
Identify the key characteristic of coordination isomers: Unlike other types of isomerism, coordination isomers involve the exchange of ligands and counterions, rather than changes in spatial arrangement or connectivity.
Differentiate coordination isomers from other isomers: Coordination isomers are not about different spatial arrangements or mirror images, which are characteristics of stereoisomers and enantiomers, respectively.
Recognize the correct statement: Among the given options, the statement 'The ligands and counterions exchange places' correctly describes coordination isomers.
Apply this understanding to similar problems: Knowing the defining feature of coordination isomers helps in identifying them in various coordination chemistry contexts.
