Tam sim no, aromatic halides tsis tau hloov pauv nucleophilic nrog ntsev tsim los ntawm phthalimide . Yog li ntawd, aromatic amines tsis tuaj yeem ua tau npaj los ntawm Gabriel phthalimide cov tshuaj tiv thaiv . Tsis tas li ntawd nws koom nrog nucleophilicsubstitution (SN2) ntawm alkyl halides los ntawm anion tsim los ntawm phthalimide.
Tib neeg kuj nug, leej twg ntawm cov amines hauv qab no Tsis tuaj yeem npaj los ntawm Gabriel phthalimide synthesis?
Gabriel phthalimide Cov tshuaj tiv thaiv yog siv rau kev hloov pauv ntawm thawj alkyl halides rau hauv thawj amines . Ntawm cov khoom sib txuas, A, B thiab D yog thawj amines (cov khoom ntawm Gabriel phthalimide tshuaj tiv thaiv). Thaum C yog tus thib ob amine ( ua tsis tau yuav muab synthesized los ntawm cov tshuaj tiv thaiv no).
Qhov twg ntawm cov amines hauv qab no tuaj yeem npaj los ntawm Gabriel synthesis? Qhov twg ntawm cov amines hauv qab no tuaj yeem npaj los ntawm Gabriel synthesis. A. Isobutyl amine B. 2-Phenylethylamine C. N-methylbenzylamine D. Aniline
- •
- • Aryl halides zoo li (ii) 2-Phenylethylamine(iii) N-methylbenzylamine thiab (iv) Aniline.
Ib yam li ntawd, koj tuaj yeem nug, yuav ua li cas cov amines tseem ceeb tau npaj los ntawm Gabriel phthalimide synthesis?
Thaum Gabriel phthalimide synthesis , cov tshuaj tiv thaiv ntawm phthalimide thiab ethanolic potassium hydroxide muab potassium ntsev ntawm phthalimide . Cov ntsev ntawm cua sov nrog alkyl halide ua raws li alkaline hydrolysis muab coj los siv thawj amine.
aniline puas tuaj yeem npaj los ntawm Gabriel phthalimide synthesis?
Aniline ua tsis tau npaj los ntawm Gabriel synthesis . Muab laj thawj. Aniline ua tsis tau npaj los ntawm txoj kev no vim aryl halides ua tsis tau txais kev hloov pauv nucleophilic nrog cov anion tsim los ntawm phthalimide.

Dab tsi ntawm impurities tuaj yeem raug tshem tawm ntawm cov organic compound los ntawm distillation?
Ua haujlwm kom raug, distillation tuaj yeem tshem tawm txog 99.5 feem pua ntawm cov impurities ntawm dej, suav nrog cov kab mob, hlau, nitrate, thiab cov khoom tawg
Koj yuav npaj ethylamine los ntawm Gabriel phthalimide synthesis li cas?
Koj tuaj yeem npaj cov amine thawj zaug los ntawm nws cov alkylazide los ntawm kev txo qis lossis los ntawm Gabriel synthesis. Hauv Gabriel synthesis, poov tshuaj phthalimide reacted nrog ib qho alkyl halide los tsim N-alkyl phthalimide. Qhov N-alkyl phthalimide no tuaj yeem hydrolyzed los ntawm aqueous acids los yog hauv paus rau hauv thawj amine
Dab tsi yog lub zog uas tuaj yeem tshwm sim ntawm qhov chaw ua si los ua kom cov khoom pib txav mus los?
Kev sib txhuam. Thaum lub ntiajteb txawj nqus yog ib qho tseem ceeb ntawm physics rau qhov chaw ua si swb, kev sib txhuam yog qhov tseem ceeb sib npaug. Kev sib txhuam ua haujlwm tiv thaiv lub ntiajteb txawj nqus kom qeeb tus neeg qhovntsej thiaj tsis mob ntawm tus swb. Kev sib txhuam yog ib qho quab yuam uas tshwm sim thaum twg ob yam khoom rub tawm rau ib leeg, xws li swb thiab ib tus neeg lub nraub qaum
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi ntawm cov yam ntxwv ntawm lub cev tuaj yeem ua rau muaj teeb meem kev thauj mus los?
Topography yog ib qho piv txwv classic ntawm cov txheeb ze uas cuam tshuam rau kev thauj mus los hauv av raws txoj hauv kev uas muaj kev sib txhuam tsawg tshaj plaws, xws li cov tiaj, hav thiab qhov chaw qis qis. Rau maritimetransportation, cov txheeb ze cov teeb meem feem ntau qeeb downcirculation xws li straits, channels los yog dej khov
