Hauv qaug zog puag / nucleophile cov tshuaj tiv thaiv (muaj zog acid) qhov kev txiav txim ntawm cov xwm txheej feem ntau yog 1. Cov kua qaub uas peb yuav siv thaum dej yog cov kuab tshuaj yuav yog sulfuric acid (H2SO4) thiab cov kua qaub uas peb yuav siv thaum haus cawv yog cov kuab tshuaj (nonaqueous) yuav yog toluenesulfonic. acid ( TSO ). Koj tuaj yeem xav txog TSO Raws li 'organic' sulfuric acid.
Tsis tas li ntawd, TsOH siv rau dab tsi?
Toluenesulfonic acid (p-toluenesulfonic acid; TSO ; p- TSO ): Ib qho aromatic sulfonic acid, feem ntau siv li muaj zog acid catalyst.
Tom qab ntawd, lo lus nug yog, TsOH ua dab tsi hauv cov tshuaj tiv thaiv? Tshooj 17: Aldehydes thiab Ketones. Nucleophilic Ntxiv rau C = O. Hom reagents: ntau tshaj ROH, catalytic p-toluenesulfonic acid (feem ntau sau ua TSO ) nyob rau hauv refluxing benzene. Aldehydes thiab ketones teb nrog ob moles ntawm cawv kom muab 1, 1-geminal diethers feem ntau hu ua acetals.
Yog li ntawd, yog TsOH muaj zog acid?
Raws li nrog rau lwm cov sulfonic kua qaub , TSO yog a muaj zog organic kua qaub . Nws yog hais txog ib lab zaug muaj zog dua tshaj benzoic kua qaub . Nws yog ib qho ntawm ob peb muaj zog acids uas yog khoom thiab, li no, conveniently hnyav.
Yuav ua li cas kom tshem tau Oh?
3 Txoj Kev Ua OH Ib Pab Pawg Zoo Tshaj Tawm
- Tig nws mus rau hauv alkyl halide los ntawm kev siv PBr3 lossis SOCl2. Qhov no yuav hloov cov cawv rau hauv alkyl bromide lossis alkyl chloride, raws li, thiab halides (ua lub hauv paus tsis muaj zog) yog cov pab pawg tawm zoo.
- Tig nws mus rau hauv alkyl sulfonate siv tosyl chloride (TsCl) lossis mesyl chloride (MsCl).
- Ntxiv kua qaub.

Puas yog ch3ch3 yog Lewis acid lossis base?
CH3CH3 tuaj yeem yog Lewis puag, thiab BBr3 tuaj yeem yog Bronsted-Lowry acid. CH3CH3 tuaj yeem yog Lewis puag, BBr3 tuaj yeem yog Bronsted-Lowry acid, thiab CH3Cl tuaj yeem yog Lewis puag
Puas yog ch4 a Lewis acid lossis base?
Ib tug xov tooj ntawm pawg 14 elemental hydrides: CH4, SiH4, GeH4 & SnH4, yog inert rau Lewis acid thiab Lewis puag reagents. (Cov hom tuaj yeem raug oxidised thiab lawv raug cuam tshuam los ntawm radicals thiab diradicals.) Yog li methane yog Lewis puag tab sis, zoo li helium, nws yog ib qho tsis tshua muaj zog proton abstractor
Guanine Base yog dab tsi?
Guanine. = Español. Guanine (G) yog ib qho ntawm plaub lub hauv paus hauv DNA, nrog rau lwm qhov peb yog adenine (A), cytosine (C), thiab thymine (T). Nyob rau hauv DNA molecule, guanine bases nyob rau ntawm ib tug strand tsim tshuaj bonds nrog cytosine bases nyob rau hauv opposite strand
Base ntsev yog dab tsi?
BASE Electrolyte Salt muab cov neeg ncaws pob nrog cov khoom siv hluav taws xob zoo dua, ua rau lawv ua kom muaj kev ua tau zoo, nyob twj ywm hydrated thiab tawm tsam qaug zog. BASE Salt lub cim crystalline daim ntawv yog yooj yim heev zom, sai sai absorbed thiab muaj nyob rau hauv cov hlab ntsha los ntxiv cov electrolytes poob hauv hws
TSOH siv rau dab tsi?
TsOH pom kev siv cov organic synthesis ua 'organic-soluble' acid catalyst. Piv txwv ntawm kev siv xws li: Acetalization ntawm ib qho aldehyde. Esterification ntawm carboxylic acids
