Carboxylic acid derivatives muaj ntau yam kev siv. Piv txwv li, ntxiv rau nws siv raws li ib tug tshuaj tua kab mob, formic kua qaub , qhov yooj yim tshaj plaws carboxylic acid , yog ua hauj lwm nyob rau hauv textile kev kho mob thiab raws li ib tug kua qaub txo tus neeg sawv cev. Acetic kua qaub yog feem ntau siv hauv kev tsim cov cellulose plastics thiab esters.
Kuj tseem paub yog, vim li cas carboxylic acids tseem ceeb?
Carboxylic acids yog thiab tseem ceeb nyob rau hauv kev tsim cov roj, crayons, thiab plastics. Cov tshuaj sib xyaw nrog cov carboxyl pawg kuj tau yooj yim hloov mus rau cov tebchaw hu ua esters, uas muaj cov hydrogen atom ntawm pawg carboxyl hloov nrog ib pawg uas muaj carbon thiab hydrogen atoms.
Ib yam li ntawd, pawg carboxyl yog dab tsi? Hauv chemistry, cov pawg carboxyl yog ib qho organic, ua haujlwm pab pawg muaj cov pa roj carbon atom uas yog ob npaug rau cov pa oxygen atom thiab sib koom ua ke rau hydroxyl pab pawg . Lwm txoj hauv kev los saib nws yog raws li carbonyl pab pawg (C = O) uas muaj hydroxyl pab pawg (O-H) txuas rau carbon atom.
Ib yam li ntawd, qhov piv txwv ntawm carboxylic acid yog dab tsi?
A carboxylic acid yog ib qho organic compound uas muaj a carboxyl pawg (C(=O)OH). Tseem ceeb piv txwv suav nrog cov amino kua qaub thiab acetic kua qaub . Deprotonation ntawm a carboxyl pab pawg muab cov carboxylate anion.
Dab tsi yog kev siv ntawm alkanoic acid?
Cov ntsiab lus hauv qab no yuav hais txog lwm yam kev siv tseem ceeb ntawm carboxylic acids:
- Kev tsim cov xab npum xav tau cov roj ntsha ntau dua.
- Kev lag luam zaub mov siv ntau cov organic acids rau kev tsim cov dej qab zib, khoom noj khoom haus thiab lwm yam.
- Hauv kev lag luam kws tshuaj organic acids tau siv ntau yam tshuaj xws li tshuaj aspirin, phenacetin thiab lwm yam.

Dab tsi yog qhov feem ntau reactive carboxylic acid derivative?
Cov sib txawv carboxylic acid derivatives muaj ntau reactivities sib txawv, acyl chlorides thiab bromides yog cov feem ntau reactive thiab amides tsawg reactive, raws li tau sau tseg nyob rau hauv cov nram qab no qualitatively xaj daim ntawv teev. Qhov kev hloov hauv reactivity yog qhov txaus ntshai
Tus neeg twg tau soj ntsuam kev mloog lus ntawm kev sib raug zoo los ntawm kev ua ib qho kev sim uas yuav tsum muaj cov tub ntxhais kawm cov ntsiab lus los tswj cov kev mob siab rau cov ntsiab lus hauv kev tshuaj xyuas kev kawm?
Milgram Shock Experiment Ib qho ntawm cov kev tshawb fawb nto moo tshaj plaws ntawm kev mloog lus hauv kev puas siab puas ntsws tau ua los ntawm Stanley Milgram, tus kws kho mob hlwb ntawm Yale University. Nws tau ua ib qho kev sim qhia txog qhov tsis sib haum xeeb ntawm kev mloog lus rau txoj cai thiab lub siab ntawm tus kheej
Dab tsi yog cov cuab yeej lossis cov txheej txheem siv los hloov cov ntaub ntawv kev ua haujlwm rau hauv cov ntaub ntawv kev ua haujlwm hauv cov txheej txheem tswj Scope?
Variance Analysis yog ib qho cuab yeej & Cov txheej txheem ntawm Kev Tswj Scope Txheej Txheem thiab Kev Ntsuas Kev Ua Haujlwm Ua Haujlwm (WPM) yog qhov tso tawm ntawm cov txheej txheem no
Puas yog ib qho kev sau ntawm cov tuam txhab ywj pheej uas siv cov ntaub ntawv thev naus laus zis los tswj hwm lawv cov txiaj ntsig cov txiaj ntsig los sib sau ua khoom lag luam lossis kev pabcuam rau kev lag luam?
Lub vev xaib muaj txiaj ntsig yog ib qho kev sau ntawm cov tuam txhab ywj pheej uas siv cov ntaub ntawv thev naus laus zis los tswj hwm lawv cov txiaj ntsig kev sib koom ua ke tsim khoom lossis kev pabcuam rau kev lag luam. Ib lub tuam txhab tuaj yeem siv kev tswj hwm ntau dua ntawm nws cov neeg xa khoom los ntawm kev muaj: ntau tus neeg muag khoom
Dab tsi yog cov khoom siv ncaj qha kev ua haujlwm thiab kev tsim khoom siv nyiaj siv ua haujlwm?
Hauv cov tuam txhab tsim khoom, cov khoom siv nyiaj siv ua haujlwm suav nrog tag nrho cov nqi tsim khoom tshwj tsis yog cov suav nrog cov khoom siv ncaj qha thiab kev ua haujlwm ncaj qha. Cov nqi tsim khoom siv nyiaj siv ua haujlwm yog cov nqi tsim khoom uas yuav tsum tau tshwm sim tab sis tsis tuaj yeem lossis tsis tuaj yeem taug qab ncaj qha rau cov khoom tshwj xeeb tsim
