Syn ntxiv : Ib ntxiv cov tshuaj tiv thaiv nyob rau hauv uas tag nrho cov tshiab bonds yog tsim nyob rau tib lub ntsej muag ntawm lub reactant molecule. Qhov no hydroboration-oxidation tshuaj tiv thaiv yog a sib ntxiv vim qhov no tshuaj tiv thaiv xa ib H thiab OH rau tib lub ntsej muag ntawm alkene.
Ib yam li ntawd, nws raug nug, ua li cas koj thiaj paub tias nws yog syn lossis anti ntxiv?
Thaum ob qho tib si atoms / pawg ntxiv rau tus tib lub ntsej muag nws yog xav txog sib ntxiv . Thaum lawv ntxiv rau opposite ntsej muag nws yog xav txog anti ntxiv . Cov qhov sib txawv ntawm tus ob yog txiav txim los ntawm qhov twg atom tus pab pawg ntxiv rau (Mark vs Anti -Mark) lossis qhov twg SIDE nws ntxiv ( syn vs tiv thaiv ).
Ib yam li ntawd, yog markovnikov syn ntxiv? 1. Hydroboration ntawm Alkenes: Hydrogen ntxiv rau "Ntau Hloov" Qhov Kawg Ntawm Cov Carbon ("anti- Markovnikov ”) Thiab Kev Txiav Txim Siab Yog “ Syn ”
Cov lus nug tseem yog, puas yog electrophilic ntxiv syn lossis anti?
Hauv cov tshuaj tiv thaiv 1 thiab 3 cov ntsiab lus ntawm HCl ntxiv rau sab nraud ntawm ob daim ntawv cog lus. Qhov no hu ua anti ntxiv . Lub stereochemistry ntawm cov tshuaj tiv thaiv 4 kuj yog tiv thaiv . Hauv cov tshuaj tiv thaiv 5 cov ntsiab lus ntawm deuterated acetic acid ntxiv rau tib sab ntawm ob daim ntawv cog lus hauv dab tsi yog hu ua sib ntxiv.
Yuav ua li cas koj txheeb xyuas tus alkene?
Ib qho kev sim yooj yim nrog dej bromine tuaj yeem siv los qhia qhov txawv ntawm ib qho alkane thiab ib qho alkene . Ib alkene yuav tig xim av bromine dej tsis muaj xim raws li cov bromine reacts nrog cov carbon-carbon ob daim ntawv cog lus. Qhov tseeb, qhov tshuaj tiv thaiv no yuav tshwm sim rau cov khoom sib txuas uas tsis muaj cov pa roj carbon-carbon ob daim ntawv cog lus.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Qhov kev sib npaug twg yog qhov tsim nyog los suav cov cua sov uas tsim los ntawm HCl NaOH cov tshuaj tiv thaiv?
Xam cov naj npawb ntawm moles ntawm lub hauv paus koj ntxiv los txiav txim siab molar tshav kub ntawm qhov nruab nrab, qhia siv qhov sib npaug Δ H = Q ÷ n, qhov twg 'n' yog tus naj npawb ntawm moles. Piv txwv li, xav tias koj ntxiv 25 mL ntawm 1.0 M NaOH rau koj HCl los ua kom muaj cua sov ntawm nruab nrab ntawm 447.78 Joules
Dab tsi yog qhov sib txawv tseem ceeb ntawm tshuaj lom neeg thiab cov tshuaj tiv thaiv nuclear Lub hlwb?
(1) Cov tshuaj tiv thaiv Nuclear cuam tshuam nrog kev hloov pauv ntawm inan atom lub nucleus, feem ntau tsim cov khoom sib txawv, nrog rau kev tawm ntawm cov hluav taws xob xws liα, β thiab gamma; lwm ray. Cov tshuaj tiv thaiv tshuaj, ntawm qhov tod tes, tsuas yog muaj kev hloov pauv ntawm cov hluav taws xob thiab tsis cuam tshuam nrog kev hloov pauv hauv cov nuclei
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
