conformational isomer; conformer
Chemistry term for molecules that differ only by rotation around single bonds. Used in organic chemistry and stereochemistry contexts.
Conformational isomers of cyclohexane include the chair form and the boat form.
In this reaction, a specific conformer is preferentially produced.
Stereoisomer, a broader term that includes both conformational isomers and configurational isomers. 配座異性体 is a subtype of 立体異性体.
Configurational isomer, which differs from conformational isomers in that interconversion requires breaking bonds, not just rotation.
Compound of 配座 (conformation) + 異性体 (isomer). The term is a direct calque from English 'conformational isomer'.
