Ob leeg tshuaj benzene thiab ethene yog unsaturated hydrocarbons tab sis tshuaj benzene yog tsawg reactive tshaj ethene vim nws kim heev delocalization uas ua rau stability. Benzene xav hloov cov tshuaj tiv thaiv ntxiv dua cov tshuaj tiv thaiv ntxiv. Ntawm qhov tod tes, ethane yog tsawg reactive tshaj benzene vim lawv saturated xwm.
Ntawm no, yog vim li cas alkenes reactive dua li benzene?
Lo lus nug: Alkenes Yog Ntau Reactive dua Benzene Thiab Kev Sib Tham Ntxiv Ntxiv, xws li Decolourizing Bromine Dej Hauv Kev Ruaj Ntseg (A) Hauv qab no, Qhov C = C Ob Chav Bond ploj lawm. Benzene Tsuas yog Reacts Nrog Br_2 nyob rau hauv qhov muaj ib tug catalyst thiab cov khoom tsuas muaj ib tug Br Atom thiab cov Benzene Nplhaib tseem nyob tsis tau.
Ib tug kuj yuav nug, uas yog ntau reactive alkyne los yog benzene? Cov tshuaj tiv thaiv ntawm tshuaj benzene yog electrophilic hloov thaum ethene raug ntxiv thiab cov tshuaj tiv thaiv polymerization. Ntawm qhov tod tes, ethane tsawg dua reactive tshaj tshuaj benzene vim lawv saturated xwm. Vim li cas alkyne tsawg dua reactive koj alkene?
Ua raws li qhov no hauv kev xav, vim li cas Ethyne thiaj li muaj zog dua li ethene?
Ethyne yog ntau reactive tshaj ethene vim nws muaj ob π-bonds uas ua rau nws qaug zog tshaj ethene … Ib qho kev txhawb nqa rau kuv cov lus teb yog qhov acidic ntawm ethyn . Ib daim ntawv cog lus yog tus feem ntau ruaj khov, li no qhov tsawg kawg nkaus reactive vim ob tug electrons ntau yooj yim nyob rau hauv lawv orbits.
Yog vim li cas Benzene tsis reactive?
Orbitals nrog tib lub zog yog piav raws li degenerate orbitals. Ntawm ntau yam tshwj xeeb ntawm tshuaj benzene , nws aromaticity yog qhov tseem ceeb contributor vim li cas nws thiaj li unreactive. Muaj delocalized electrons saum toj thiab hauv qab lub dav hlau ntawm lub nplhaib, uas ua rau tshuaj benzene tshwj xeeb ruaj khov.

Yog vim li cas magnesium tsawg reactive dua sodium?
Sodium yog cov hlau electropositive ntau dua uas txhais tau hais tias nws "ntxub cov hluav taws xob ntau dua li magnesium yog li nws xav tau lub zog tsawg dua rau chuck electrons dua li magnesium. Cov no yog cov ntsiab lus tseem ceeb uas piav qhia vim li cas cov hlau sodium yog ntau dua li cov hlau magnesium
Vim li cas 9 Fluorenone ntau dua polar dua fluorene?
Cov tshuab hnyav tau cais cov fluorene thiab 9-fluorenone raws li lawv qhov sib txawv ntawm cov qauv thiab polarity. Nyob rau hauv txoj cai, cov tshuaj compound uas ntws los ntawm kem ntawm ib tug ceev ceev yog ntau tsis-polar; Yog li ntawd, nyob rau hauv cov ntaub ntawv no fluorene yog ntau tsis-polar tshaj 9-fluorenone
Vim li cas alkali thiab alkaline ntiaj teb hlau yog ntau reactive?
Vim li cas alkaline ntiaj teb hlau tsis tshua muaj zog dua li alkali hlau? A: Nws yuav siv zog ntau dua los tshem tawm ob lub valence electrons los ntawm ib lub atom tshaj li ib lub valence electron. Qhov no ua rau alkaline ntiaj teb hlau nrog lawv ob lub valence electrons tsawg reactive dua alkali hlau nrog lawv ib valence electron
Yog vim li cas thermal khiav ntawm atmospheric gas ntau yooj yim dua los ntawm lub hli dua los ntawm lub ntiaj teb?
Yog vim li cas thermal khiav ntawm atmospheric gas ntau yooj yim dua los ntawm lub hli dua los ntawm lub ntiaj teb? Vim lub hli lub ntiajteb txawj nqus muaj zog npaum li lub ntiaj teb. Cov pa oxygen tso tawm los ntawm lub neej raug tshem tawm ntawm qhov chaw los ntawm cov tshuaj lom neeg nrog cov pob zeb nto kom txog thaum lub pob zeb nto tuaj yeem nqus tsis tau ntxiv
Vim li cas cov kab mob feem ntau tsim cov xeeb ntxwv ntau dua li muaj sia nyob?
Cov kab mob tsim cov xeeb ntxwv ntau dua li qhov muaj sia nyob. Cov kab mob tuaj yeem tuag los ntawm ntau yam ua rau: kab mob, kev tshaib plab, thiab noj, thiab lwm yam. Ib puag ncig tsis tuaj yeem txhawb nqa txhua yam kabmob uas yug los. Ntau tus tuag ua ntej lawv muaj peev xwm rov tsim dua
