Solub poov tshuaj carbonate hauv 20 ml dej hauv 100 ml Erlenmeyer hwj. Txog 3.5 mL ntawm acetone ntxiv rau cov tshuaj no. Ntxiv cov hmoov iodine rau hauv lub hwj Erlenmeyer, ua nco ntsoov do cov sib tov. Muab qhov sib tov no tso rau hauv ib da dej sov ntawm qhov kub ntawm 70 mus rau 80 degrees Celsius rau li 15 feeb.
Ib yam li ntawd, koj ua li cas iodoform xeem?
Cov Iodoform Test . Yuav ua li cas tus xeem : Peb tee ntawm cov tshuaj uas yuav tsum tau kuaj yog ntxiv rau 3 ml dej thiab 10 tee ntawm KI / kuv2 tov (dub liab doog-xim av tov). 10% NaOH tov yog ntxiv dropwise kom txog thaum cov xim tsaus ntawm cov tshuaj yuav ploj mus rau daj.
Tsis tas li ntawd, acetone puas muab iodoform kuaj? Tsuas yog aldehyde tuaj yeem dhau qhov no tshuaj tiv thaiv yog acetone vim nws tsuas yog aldehyde nrog methyl txuas rau alpha txoj hauj lwm ntawm carbonyl. Tsuas yog ib qho aldehyde thiab tsuas yog ib qho cawv cawv xwb muab ib tug zoo iodoform xeem.
Ib yam li ntawd ib tug yuav nug, cov tebchaw twg tuaj yeem muab iodoform kuaj?
Cov tebchaw uas muab kev kuaj iodoform zoo yog cov nrog Alpha methyl pawg. Yuav kom meej meej, Ethanal ( Acetaldehyde ) thiab methyl ketones . Ethanal yog tus xwb aldehyde uas muab qhov zoo iodoform kuaj. Yog li, ketone lub cev aldehyde nrog cov qauv -COCH3 kuj qhia tau zoo.
iodoform yog dab tsi?
Ua ntej npaj rau xyoo 1822, iodoform yog tsim los ntawm electrolysis ntawm aqueous daws uas muaj acetone, inorganic iodides, thiab sodium carbonate.

Cov pob zeb sedimentary tau npaj li cas?
Sedimentary pob zeb tuaj yeem muab faib ua ob pawg. Qhov thib ib yog pob zeb detrital, uas yog los ntawm kev yaig thiab tsub zuj zuj ntawm pob zeb tawg, sediment, los yog lwm yam ntaub ntawv - categorized nyob rau hauv tag nrho raws li detritus, los yog khib nyiab. Lwm qhov yog pob zeb tshuaj lom neeg, tsim los ntawm kev tawg thiab nag lossis daus ntawm cov ntxhia
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
Kuv yuav npaj li cas rau O'Level chemistry?
Nyeem ntxiv los tshawb txog Sheryl's 5 lub tswv yim txhawm rau txhawm rau 'O' Qib Chemistry Paper 2. Yuav kom tau qhab nia zoo, cov tub ntxhais kawm yuav tsum: paub lawv cov ntsiab lus zoo. xyaum tswj lub sijhawm. txheeb xyuas hom lus nug thiab cov kev xav tau nrog precision. teb txhua lo lus nug kom raug
Yuav ua li cas ua ammonium molybdate reagent?
Dissolve 1.0 g ntawm ammonium molybdate nyob rau hauv 100 ml ntawm 2 M H2SO4. Kev daws teeb meem (2). Dissolve 0.10 g ntawm hydrazine sulfate hauv 100 ml dej. Tam sim ntawd ua ntej siv, sib tov 10 ml ntawm kev daws (1) nrog 10 ml ntawm kev daws (2), thiab dilute mus rau 100 ml nrog dej
Yuav ua li cas silica gel npaj rau kem chromatography?
Kev npaj ntawm Kem: Npaj slurry ntawm silica gel nrog cov kuab tshuaj tsim nyog & ncuav maj mam muab tso rau hauv kem. Qhib qhov nres qaib & cia qee qhov hnyav kom ntws tawm. Txheej ntawm cov kuab tshuaj yuav tsum nco ntsoov npog cov adsorbent; txwv tsis pub cov kab nrib pleb yuav tsim nyob rau hauv kab
