Pim cawv thiab methanol react tsim alkyl halides nyob rau hauv acidic tej yam kev mob los ntawm an SN2 mechanism. … Lub halide ion ces tshem tawm cov dej molecule (ib pab pawg zoo) los ntawm cov pa roj carbon; Qhov no ua rau alkyl halide: Ib zaug ntxiv, yuav tsum muaj kua qaub.
Yuav ua li cas los ntawm alkyl halide mus rau cawv?
- Alkyl halides tuaj yeem hloov mus rau cawv siv dej lossis hydroxide raws li nucleophile.
- Mechanism yog ib qho yooj yim nucleophilic hloov pauv.
- Kev tshem tawm cov tshuaj tiv thaiv tuaj yeem yog teeb meem tshwj xeeb yog tias siv hydroxide.
- Tsis yog tshwj xeeb tshaj yog alkyl halides feem ntau npaj los ntawm cawv.
Yuav ua li cas nrog alkyl halides?
Alkyl halides tau txais nucleophilic hloov pauv cov tshuaj tiv thaiv Hloov cov tshuaj tiv thaiv tuaj yeem ua raws SN1 lossis SN 2 mechanisms. Ob lub tshuab ua raws li cov xwm txheej sib txawv thiab muab cov khoom sib txawv. Alkyl halides kuj tsim ib qho tseem ceeb Grignard reagent uas feem ntau siv los ua carbon - carbon bonds.
Yuav ua li cas tshwm sim yog tias cawv dhau los ua alkyl halide?
Cawv tsuas tuaj yeem dhau mus hloov cov tshuaj tiv thaiv tsim cov alkyl halides yog tias cawv thawj zaug hloov mus rau hauv dej. Qhov no ua rau cov cawv yog ib pab pawg tawm zoo dua. Cov dej cawv thawj zaug tau txais SN2 cov tshuaj tiv thaiv, uas tshwm sim hauv ib kauj ruam nrog kev tawm tsam halide thiab ncaws tawm dej.
Vim li cas alkyl halides soluble hauv cawv?
Muaj tsawg dua hydrogen-bonding lub sijhawm hauv cov kua dej cawv ntau dua li cov dej ntshiab. Feem ntau, alkyl halides nyiam poob rau hauv qhov qis-rau-nruab nrab polarity ntau.
