Cov pawg carboxylic acid muaj C=O. (ib carbonyl) nrog ib pab pawg OH ntxiv nrog rau cov pa roj carbon. … Cov hluav taws xob hauv O-H daim ntawv cog lus nyob tom qab, muab cov nqi tsis zoo rau qhov tshwm sim carboxylate anion. Cov ntsev uas tsim yog ntau dua dej soluble.
YPuas carboxylate soluble hauv dej?
Solubility. Solubility ntawm carboxylic acids nyob rau hauv dej yog zoo ib yam li cov cawv, aldehydes, thiab ketones. Acids nrog tsawg dua li tsib carbons yaj hauv dej; cov uas muaj qhov hnyav dua molecular yog insoluble vim qhov loj hydrocarbon feem, uas yog hydrophobic.
YPuas carboxylate anions soluble hauv dej?
Water-soluble carboxylic acids ionize me ntsis hauv dej los tsim cov kua qaub me ntsis. Lawv cov kev daws teeb meem aqueous nthuav tawm cov yam ntxwv ntawm cov kua qaub, xws li hloov litmus ntawm xiav mus rau liab. Cov anion tsim thaum carboxylic acid dissociates hu ua carboxylate anion (RCOO-).
Qhov twg ntawm carboxylic acids los yog carboxylate ntsev yog soluble hauv dej ntau tshaj?
Cov ntaub ntawv no kuj qhia tau tias cov dej-solubility ntawm carboxylate ntsev ntau dua li cov carboxylic acid sib xws. Qhov kev solubility siab dua no yog vim muaj qhov ionic ntawm pawg ua haujlwm thiab kev sib cuam tshuam ntawm pawg neeg ua haujlwm tsis zoo ( CH 3 (CH 2)4CO2 -,piv txwv) nrog dej.
Vim li cas carboxylic acids tsis soluble hauv dej?
Ceebtoom: Cov carboxylic acids siab dua tsis tau yooj yim soluble hauv dej vim ua kom hydrophobicity ntawm alkyl saw. Cov saw hlau ntev dua no yuav zoo dua soluble hauv cov kuab tshuaj tsawg dua li ethers lossis cawv.
