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.
