-ane

释义

-ane, suffix
1. Occas. Eng. ad. L. -ānus, perh. orig. a. Fr. -ain; used, chiefly for sake of distinction, in words that have a parallel form in -an, as germane, humane, urbane, also in mundane.
2. Chemical formative.
†a. Arbitrary ending proposed by Davy for names of monochlorides, now obsolete. (See Watts Dict. Chem. IV. 121.)
b. Org. Chem. In the systematic nomenclature proposed by Hofmann 1866, the formative of the names of the saturated hydrocarbons of composition C_nH₂_n _{+ 2}, also called paraffines; as Methane CH₄ (formerly Methyl hydride), Ethane C₂H₆, Propane C₃H₈, Butane or Quartane C₄H₁₀, Pentane C₅H₁₂, Hexane C₆H₁₄, etc. [The formation is purely imitative; the Greek feminine patronymic endings -ene, -ine, -one, (-ήνη, -ίνη, -ώνη) were already in partial use in naming hydrocarbon derivatives. Hofmann proposed the adoption of the entire vowel series -ane, -ene, -ine, -one, -une, and the strict application of these to hydrocarbons of the types C_nH₂_n₊₂, C_nH₂_n, C_nH₂_n_-2, C_nH₂_n_-4, C_nH₂_n_-6, or their analogues, respectively. So far as concerns the first three members this has been generally adopted.]
