Nws yog lub xub ntiag ntawm ob daim ntawv cog lus no ua rau alkenes ntau reactive tshaj alkanes. Alkenes undergo ib qho ntxiv cov tshuaj tiv thaiv nrog dej nyob rau hauv lub xub ntiag ntawm ib tug catalyst los tsim ib tug cawv. Hom kev sib ntxiv no hu ua hydration. Cov dej yog ntxiv ncaj qha rau carbon - carbon ob daim ntawv cog lus.
Tib neeg kuj nug, ua li cas thaum propene reacts nrog dej?
Propene reacts nrog dej nyob rau hauv lub xub ntiag ntawm ib tug dilute, muaj zog acid los tsim propanol. Lub dilute, muaj zog acid tsis coj qhov chaw nyob rau hauv lub tshuaj tiv thaiv nws tus kheej. Qhov ntxiv ntawm a dej molecule rau lwm molecule yog hu ua hydration tshuaj tiv thaiv . Lub hydration ntawm alkene yog ib qho piv txwv ntawm kev ntxiv tshuaj tiv thaiv.
Ib tug kuj yuav nug, yog hydration ntawm alkenes electrophilic ntxiv? Electrophilic hydration yog txoj cai ntxiv electrophilic hydrogen los ntawm cov uas tsis yog-nucleophilic muaj zog acid (ib tug reusable catalyst, piv txwv li muaj xws li sulfuric thiab phosphoric acid) thiab siv qhov tsim nyog kub los ua txhaum lub alkene cov ob daim ntawv cog lus.
hydration yog ib qho tshuaj tiv thaiv ntxiv?
Hauv chemistry, a hydration tshuaj tiv thaiv yog tshuaj tshuaj tiv thaiv nyob rau hauv uas ib yam khoom ua ke nrog dej. Nyob rau hauv cov organic chemistry, dej yog ntxiv rau lub substrate unsaturated, uas feem ntau yog alkene los yog ib qho alkyne. Hom no tshuaj tiv thaiv yog ua hauj lwm industrially los tsim ethanol, isopropanol, thiab 2-butanol.
Puas yog alkenes soluble hauv dej?
Alkenes yog sib dua li dej thiab yog insoluble hauv dej vim lawv tsis yog -polar yam ntxwv. Alkenes tsuas yog soluble hauv cov kuab tshuaj tsis muaj polar.

Yuav ua li cas thaum lub hauv paus ntxiv rau dej?
Ntxiv dej rau cov kua qaub los yog lub hauv paus yuav hloov nws cov pH. Dej feem ntau yog cov dej molecules yog li ntxiv dej rau hauv cov kua qaub los yog hauv paus txo cov concentration ntawm ions hauv cov tshuaj. Ib yam li ntawd, thaum alkali diluted nrog dej, qhov concentration ntawm OH - ions txo
Yuav ua li cas ntxiv bromine rau 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
Vim li cas bromine Decolourise thaum ntxiv rau alkene?
Bromine rhuav tshem ob daim ntawv cog lus ntawm cyclohexene (thiab tag nrho cov alkenes), ua rau cov qauv molecular hloov thiab yog li cov molecule lub zog hloov. Bromine yog reactive heev vim hais tias nws tuaj yeem tsim cov dawb radicals, uas txhais tau hais tias muaj ib qho molecule ntawm Br nrog ib qho tsis sib xws ntawm electrons
Thaum HBr ntxiv rau alkene nyob rau hauv muaj h2o2?
Qhov no yog hu ua Markovnikov's Rule. Vim hais tias HBr ntxiv rau 'txoj kev tsis ncaj ncees nyob ib puag ncig' nyob rau hauv lub xub ntiag ntawm cov organic peroxides, qhov no feem ntau hu ua cov nyhuv peroxide lossis anti-Markovnikov ntxiv. Thaum tsis muaj peroxides, hydrogen bromide ntxiv rau propene ntawm ib qho kev sib ntxiv ntawm electrophilic
Yuav ua li cas tshwm sim thaum koj ntxiv ib tug qaug zog acid rau dej?
Thaum cov kua qaub uas tsis muaj zog ntxiv rau hauv dej, cov ntaub ntawv sib npaug sib npaug hauv cov kua qaub molecules, HA (aq), hnov mob nrog cov dej ua kua los tsim cov aqueous hydronium ions thiab aqueous anions, A-(aq). Cov tom kawg yog tsim thaum cov kua qaub molecules poob H + ions rau dej
