Nyob rau hauv carboxylic acids thiab lawv derivatives, lub carbonyl pawg yog txuas rau ib qho ntawm halogen atoms los yog rau pab pawg muaj cov atom xws li oxygen, nitrogen, lossis sulfur. Cov atoms no cuam tshuam rau carbonyl pawg , tsim kev ua haujlwm tshiab pab pawg nrog cov khoom tshwj xeeb.
Hais txog qhov no, pawg carbonyl ua dab tsi?
Nyob rau hauv biology, a carbonyl pawg nyob rau hauv ib lub molecule tso cai rau nws mus rau ntau yam kev cuam tshuam tsim nyog los tswj lub neej. Muaj ntau hom roj ntsha molecules muaj a carbonyl pawg , uas tso cai rau lub cell muaj peev xwm los tsim cov molecules tshiab thiab hloov cov molecule nrog ib tug xov tooj ntawm lwm yam functional. pab pawg.
Ib yam li ntawd, cov ntsiab lus twg ua rau pawg carbonyl? Cov Carbonyl Group. Ib pawg carbonyl yog ib pawg tshuaj lom neeg ua haujlwm ua haujlwm muaj li ntawm a carbon atom dual-bonded rau ib oxygen atom [C=O] Cov pawg carbonyl yooj yim tshaj plaws yog aldehydes thiab ketones feem ntau txuas rau lwm tus carbon compound.
Ib yam li ntawd, koj ua li cas rau carbonyl?
Carbonyl pawg hauv aldehydes thiab ketones tuaj yeem oxidized rau daim ntawv Cov tebchaw tom ntej "qib oxidation", uas yog carboxylic acids. Ntxiv dej rau ib qho aldehyde lossis ketone muab cov khoom hu ua hydrate lossis lub pov haum-diol (ob pawg -OH ntawm tib cov pa). Cov tshuaj tiv thaiv yog ob qho tib si acid-catalyzed thiab base-catalyzed.
Muaj pes tsawg carbonyl pawg?
Ketones. Hauv ketone lub cev, pawg carbonyl muaj ob hydrocarbon pab pawg txuas.
Pom zoo:
Vim li cas cov pab pawg carbonyl tseem ceeb?
Lawv tuaj yeem pom hauv ntau pawg ua haujlwm sib txawv, xws li aldehydes, ketones, esters, thiab ntau ntxiv. Ib pawg carbonyl tuaj yeem ua rau kom lub melting lossis boiling point ntawm lub compound. Nws tau piav raws li polar thiab reactive, thiab cov nqi tsis zoo thiab zoo ntawm carbonyl pab txhawb rau polarity
Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?
Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv
Kuv yuav ua li cas thiaj tsim tau ib daim ntawv pov thawj hauv ib pawg?
Nyob rau ntawm Pawg Neeg Saib Xyuas Kev Xaiv Kev Xaiv Tsa, xaiv Xaiv Pawg neeg tim khawv. Nyem Next mus ntxiv. Ntawm Pawg Neeg Saib Xyuas Pawg Neeg Saib Xyuas, xaiv Configure a disk tim khawv thiab tom qab ntawd nyem Next. Nyob rau ntawm Configure Storage Witness vaj huam sib luag, xaiv pawg disk uas ntxiv rau pawg pawg, thiab tom qab ntawd nyem Next
Yuav ua li cas compound yuav tsim yog Aluminium thiab oxygen tau ua ke?
Aluminium tuaj yeem hnov mob nrog cov pa oxygen los tsim cov txhuas oxide (Al_2O_3)
Qhov nruab nrab ntawm pawg thiab hauv pab pawg txhais li cas?
Muaj ob txoj hauv kev los saib cov ntaub ntawv hais txog cov pab pawg no. Qhov sib txawv ntawm pab pawg qhia tias ob lossis ntau pawg sib txawv li cas, qhov sib txawv hauv pab pawg qhia qhov sib txawv ntawm cov kev kawm uas nyob hauv tib pab pawg. Nyob rau hauv-pab pawg sib txawv tuaj yeem tshwm sim thaum saib ntawm kev tshawb fawb ntawm pab pawg
