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.

Thaum cov roj nitrogen reacts nrog hydrogen gas ammonia gas tsim?
Nyob rau hauv lub thawv muab, ammonia yog tsim los ntawm kev sib xyaw ntawm rau moles ntawm nitrogen gas thiab rau moles ntawm hydrogen gas. Hauv cov tshuaj tiv thaiv no, plaub moles ntawm ammonia yog tsim los ntawm kev noj ob moles ntawm nitrogen gas
Yuav ua li cas tshwm sim thaum bromine reacts nrog ib tug alkene?
Alkenes hnov mob hauv qhov txias nrog cov kua ntshiab bromine, lossis nrog kev daws ntawm bromine hauv cov kuab tshuaj organic xws li tetrachloromethane. Qhov ob daim ntawv cog lus tawg, thiab ib qho bromine atom ua txuas rau txhua cov pa roj carbon. Cov bromine poob nws cov xim liab-xim av kom muab cov kua tsis muaj xim
Yuav ua li cas tshwm sim thaum sodium reacts nrog hydrochloric acid?
Sodium hlau reacts nrog hydrochloric acid los ua ntsev thiab hydrogen gas. Qhov no txhais tau hais tias koj cov reactants yuav yog sodium hlau thiab hydrochloric acid, vim cov no yog cov khoom uas tau hloov mus rau hauv cov ntsev thiab hydrogen gas
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
