incazelo yomkhiqizo
Kodwa-2-ene i-acyclic alkene enama-athomu ekhabhoni amane. I-alkene elula kakhulu ekhombisa i-cis/trans-isomerism (eyaziwa nangokuthi (E/Z) -isomerimmu); okungukuthi, ikhona njengama-isomers amabili ejiyomethri cis-kodwa-2-ene ((Z)-kodwa-2-ene) kanye ne-trans-kodwa-2-ene ((E)-kodwa-2-ene).
Ama-isomer amabili anzima kakhulu ukuwahlukanisa ngokuhluza ngenxa yokuba seduze kwamaphoyinti awo abilayo (~4 °C we-cis kanye no-~1 °C we-trans[5]). Kodwa-ke, ukuhlukana akudingekile kuzilungiselelo eziningi zezimboni, njengoba womabili ama-isomer aziphatha ngendlela efanayo ekuphenduleni okuningi okufunayo. Ingxube evamile yezimboni kodwa-2-ene ingu-70% (Z)-kodwa-2-ene (cis-isomer) kanye no-30% (E)-kodwa-2-ene (i-trans-isomer). I-Butane kanye ne-but-1-ene ukungcola okuvamile, okukhona ku-1% noma ngaphezulu kuzingxube zezimboni, eziqukethe namanani amancane e-isobutene, i-butadiene ne-butyne.
