Wikidata usage instructions
Do not use this item in the chemical class hierarchy. “Substituent” is not a structural class: it describes a group’s relation to a parent structure, not its constitution, so almost any univalent group can be a substituent. As a value of “subclass of” (P279) or “instance of” (P31) it carries no information and creates spurious multiple inheritance. Use a structural class under “chemical group” (Q23005640) instead., Nie używaj tego elementu w hierarchii klas chemicznych. „Podstawnik” nie jest klasą strukturalną – określa relację grupy do struktury macierzystej, a nie jej budowę, dlatego podstawnikiem może być niemal dowolna grupa jednowartościowa. Jako wartość „podklasa dla” (P279) lub „jest to” (P31) nie wnosi informacji i tworzy pozorne wielodziedziczenie. Zamiast tego użyj klasy strukturalnej spod „grupa chemiczna" (Q23005640).[5][6]
