Thaum acetaldehyde tau rhuab nrog Fehling cov tshuaj, ib lub pob liab liab yog tsim.
Yuav ua li cas thaum aldehyde reacts nrog Fehling tov?
Nws kuj yog siv los ua kev ntsuas kom txo qis thiab tsis txo cov suab thaj. Cov nag los tsim yog xim liab thiab tsuas yog muab thaum Fehling qhov kev sim ua tiav rau aldehyde. Yog li, cov nag lossis daus liab tsim thaum Fehling cov tshuaj tiv thaiv nrog aldehyde yog [C{u_2}O]. Yog li, kev xaiv A yog cov lus teb raug.
Thaum acetaldehyde rhuab nrog Fehling cov tshuaj nws muab?
[SOLVED] Thaum acetaldehyde tau rhuab nrog Fehling cov tshuaj, ib lub pob liab liab yog tsim.
YPob aldehydes teb nrog Fehling's reagent?
Fehling's Test &Fehling's Reagent
Cov tshuaj tiv thaiv yuav tsum tau cua sov ntawm aldehyde nrog Fehling's Reagent uas yuav ua rau tsim cov xim liab-xim av precipitate. Yog li, cov tshuaj tiv thaiv ua rau tsim cov carboxylate anion. Txawm li cas los xij, aromatic aldehydes tsis hnov mob rau Fehling's Test
Fehling kua Test rau aldehyde yog dab tsi?
Fehling cov tshuaj yog cov tshuaj siv los sib txawv ntawm cov dej soluble aldehyde thiab ketone functional pawg. Cov tshuaj yuav tsum tau kuaj yog rhuab ua ke nrog Fehling cov tshuaj; cov nag lossis daus liab qhiamuaj aldehyde. Ketones (tshwj tsis yog alpha hydroxy ketones) tsis hnov mob.
