Assign them with “subject has role” (P2868), not with “subclass of” (P279). State the group’s constitution separately, using a structural class under “chemical group” (Q23005640).'}[16].
  • functional group's Wikidata usage instructions is recorded as {'lang': 'pl', 'text': 'Ta klasa i jej podklasy opisują funkcję, jaką grupa pełni w cząsteczce, a nie jej budowę – ten sam fragment strukturalny bywa grupą funkcyjną albo nie, zależnie od struktury macierzystej i rozważanej reakcji. Przypisuj je za pomocą „podmiot ma rolę” (P2868), a nie „podklasa dla” (P279). Budowę grupy opisz osobno, klasą strukturalną spod „grupa chemiczna” (Q23005640).'}[17].
