Raws li nrog tag nrho cov alkenes, unsymmetrical alkenes nyiam propene react nrog hydrogen bromide nyob rau hauv txias. Ob daim ntawv cog lus tawg thiab a hydrogen atom xaus mus txuas rau ib qho ntawm cov carbons thiab ib qho bromine atom rau lwm tus. Nyob rau hauv cov ntaub ntawv ntawm propene , 2-bromopropane yog tsim.

Ib yam li ntawd, koj tuaj yeem nug, yuav ua li cas thaum alkenes hnov mob nrog hydrogen?

Ib qho piv txwv ntawm ib alkene ntxiv tshuaj tiv thaiv yog ib txoj kev hu ua hydrogenation. In a hydrogenation tshuaj tiv thaiv , ob hydrogen atoms raug ntxiv hla ob daim ntawv cog lus ntawm ib qho alkene , ua rau saturated alkane. A hydrogen atom yog ces pauv mus rau lub alkene , tsim ib daim ntawv cog lus C-H tshiab.

Tom qab, lo lus nug yog, yuav ua li cas tshwm sim thaum propene reacts nrog chlorine? Thaum twg tshuaj chlorine yog ntxiv rau ib alkene nyob rau hauv aqueous (dej) tov, lwm yam khoom loj dua li cov khoom dichloro ntxiv yog feem ntau pom. Piv txwv li, propene reacts nrog dej tshuaj chlorine los tsim 1-chloro-2-propanol ua cov khoom loj.

Hauv qhov no, cov tshuaj twg yuav qhia ntxiv cov tshuaj tiv thaiv nrog hydrogen?

Alkenes

Hom tshuaj tiv thaiv dab tsi ua rau propene?

Propene raug mob combustion cov tshuaj tiv thaiv zoo ib yam li lwm cov alkenes. Thaum muaj cov pa oxygen txaus lossis ntau dhau, propene hlawv los ua dej thiab carbon dioxide.
