Koma-2-ene ndi acyclic alkene yokhala ndi ma atomu anayi a kaboni. Ndilosavuta alkene kusonyeza cis/trans-isomerism (imadziwikanso kuti (E/Z) -isomerism); ndiko kuti, ilipo ngati ma isomers awiri a geometric cis-but-2-ene ((Z)-but-2-ene) and trans-but-2-ene ((E)-but-2-ene).
Ma isomers awiriwa ndi ovuta kwambiri kuwalekanitsa ndi distillation chifukwa cha kuyandikira kwa malo otentha (~4 °C kwa cis ndi ~1 °C kwa trans[5]). Komabe, kulekana sikofunikira m'mafakitale ambiri, chifukwa ma isomers onsewa amachita chimodzimodzi muzochita zambiri zomwe mukufuna. Kusakaniza kwa mafakitale koma-2-ene ndi 70% (Z)-koma-2-ene (cis-isomer) ndi 30% (E)-koma-2-ene (trans-isomer). Butane ndi but-1-ene ndi zonyansa zofala, zomwe zimapezeka pa 1% kapena kupitilira muzosakaniza zamakampani, zomwe zimakhalanso ndi isobutene, butadiene ndi butyne.
