Empa-2-ene ke alkene ea acyclic e nang le liathomo tse 'nè tsa carbon. Ke alkene e bonolo ka ho fetisisa e bontšang cis/trans-isomerism (e tsejoang hape e le (E/Z) -isomerism); ke hore, e teng e le li-isomers tse peli tsa geometri cis-but-2-ene ((Z)-but-2-ene) le trans-but-2-ene ((E)-but-2-ene).
Li-isomers tse peli li thata haholo ho aroloa ka distillation ka lebaka la ho ba haufi ha lintlha tsa tsona tse belang (~4 °C bakeng sa cis le ~1 °C bakeng sa trans[5]). Leha ho le joalo, karohano ha e hlokahale maemong a mangata a indasteri, kaha li-isomers ka bobeli li sebetsa ka mokhoa o ts'oanang ho tse ngata tse lakatsehang. Motsoako o tloaelehileng oa indasteri empa-2-ene ke 70% (Z)-but-2-ene (cis-isomer) le 30% (E)-but-2-ene (trans-isomer). Butane le but-1-ene ke litšila tse tloaelehileng, tse teng ho 1% kapa ho feta metsoakong ea indasteri, e nang le palo e nyane ea isobutene, butadiene le butyne.
