同義詞
  • isomeric

    broader chemistry term; metameric refers to one specific structural relationship

文法句型

metameric + compound/ether/pair

用法筆記

Mostly found in specialist chemistry writing about compounds with the same formula but different carbon-group placement around one functional center.

常見錯誤

❌Any two compounds with the same formula are metameric.
✅Only some same-formula compounds are metameric, depending on how the groups are arranged around the functional center.
💡This sense is narrower than the general idea of isomerism.
