sharaxaada alaabta
Laakiin-2-ene waa alkene acyclic ah oo leh afar atamka kaarboon. Waa alkene ugu fudud oo muujinaya cis/trans-isomerism (sidoo kale loo yaqaan (E/Z) -isomerism); taas oo ah, waxay u jirtaa sidii laba joomatari isomers cis-but-2-ene ((Z)-laakin-2-ene) iyo trans-but-2-ene ((E)-laakin-2-ene).
Labada isomers aad bay u adag tahay in lagu kala saaro kala-soocidda sababtoo ah u dhowaanshaha dhibcahooda karkaraya (~ 4 ° C cis iyo ~ 1 ° C ee trans[5]). Si kastaba ha ahaatee, kala-tagashadu waa mid aan loo baahnayn inta badan goobaha warshadaha, maadaama labada isomers ay u dhaqmaan si isku mid ah inta badan falcelinta la rabo. Isku dhafka warshadaha caadiga ah laakiin-2-ene waa 70% (Z) -laakin-2-ene (cis-isomer) iyo 30% (E) -laakin-2-ene (trans-isomer). Butane iyo but-1-ene waa wasakh caadi ah, oo ku jira 1% ama ka badan isku darka warshadaha, kaas oo sidoo kale ka kooban xaddi yar oo isobutene, butadiene iyo butyne.
