Univalent groups containing carbon, which are thus organic, but which have their free valence at an atom other than carbon. This collective term is seldom used; specific subclasses are more frequently encountered (organothio- or organylthio, organogermanium- or organylgermanium groups). The synonymous term organoelement groups is occasionally encountered. E.g. phenoxy, acetamido, pyridinio (C5H5N+-), thiocyanato (N![[triple bond]](/img5/m_files/TRIPLEB.gif)
C-S-), trimethyl silyl; but not hydroxyphenyl, aminoacetyl. Cf. organyl.
