Raws li tag nrho cov alkenes, unsymmetrical alkenes zoo li propene react nrog hydrogen bromide hydrogen bromide Infobox references. Hydrobromic acid yog cov kua qaub uas muaj zog tsim los ntawm kev ua kom cov diatomic molecule hydrogen bromide (HBr) hauv dej. "Ntawv boiling" hydrobromic acid yog ib tug aqueous tov uas distils ntawm 124.3 ° C thiab muaj 47.6% HBr los ntawm loj, uas yog 8.77 mol / L. https://en.wikipedia.org › wiki › Hydrobromic_acid
Hydrobromic acid - Wikipedia
nyob rau hauv txias. Qhov ob daim ntawv cog lus tawg thiab hydrogen atom xaus mus txuas rau ib qho ntawm cov carbons thiab ib qho bromine atom mus rau lwm qhov. Nyob rau hauv rooj plaub ntawm propene,2-bromopropaneyog tsim.
Yuav ua li cas thaum alkene reacts nrog hydrogen?
Ib qho piv txwv ntawm cov tshuaj tiv thaiv alkene ntxiv yog cov txheej txheem hu ua hydrogenation. Nyob rau hauv cov tshuaj tiv thaiv hydrogenation, ob lub atoms hydrogen tau ntxiv hla ob daim ntawv cog lus ntawm alkene, ua rau muaj cov alkane saturated. … Cov cua sov tso tawm yog hu ua cua sov ntawm hydrogenation, uas yog ib qho kev qhia ntawm ib tug molecule stability.
Lub npe ntawm cov khoom loj tsim yog dab tsi thaum tab sis 1 ene reacts nrog hydrogen chloride?
Qhov no ua rau haloalkane. Tshwj xeeb tshaj yog, qhov no haloalkane yog 2-chlorobutane. Yog li cov khoom loj tsim los ntawm cov tshuaj tiv thaiv ntawm but-1-ene nrog hydrogen chloride yog 2-chlorobutane.
YYuav ua li cas yog propene plus hydrogen?
Alkene + hydrogen →alkane
Qhov no yog hu ua hydrogenation, thiab nws xav tau lub catalyst. Piv txwv li: Propene + hydrogen → propane.
hom tshuaj tiv thaiv twg yuav tshwm sim ntawm propene thiab HCl?
Ib yam ntxiv cov tshuaj tiv thaiv tuaj yeem ua piv txwv los ntawm hydrochlorination ntawm propene (ib qho alkene), uas qhov sib npaug yog CH 3 CH=CH2 + HCl → CH3C+HCH3+ Cl− → CH3CHClCH3.
