[f. Gr. ἕξ six + -ane.]
The paraffin of the hexacarbon series, C6H14; of this there are five forms. So hexaˈnoic a. = caproic a.; ˈhexanoyl [-oyl], the radical C5H11CO{b1} of hexanoic acid; also called caproyl; hexene |ˈhɛksiːn|, the olefine of the hexacarbon series (C6H12), also called hexylene, homologous and polymeric with ethene; it exists in numerous metameric forms; hexine |ˈhɛksaɪn|, the hydrocarbon C6H10 of the same series; hexoic acid, C6H12O2, the same as caproic acid; heˈxoylene, one of the isomeric forms of hexine.
