Cov yam ntxwv ntawm cov qauv molecular ntawm Oxalic Acid

Cov qauv molecular ntawm oxalic acid tsim lub hauv paus ntawm nws cov khoom siv tshuaj lom neeg. Cov qauv, oxalic acid muaj ob pawg carboxyl (-COOH) sib txuas ncaj qha rau ib leeg, uas tuaj yeem sawv cev los ntawm cov mis condensed HOOC-COOH. Txhua pawg carboxyl yog tsim los ntawm pawg carbonyl (C = O) thiab pawg hydroxyl (-OH), ib qho qauv uas muab oxalic acid cov yam ntxwv ib txwm muaj ntawm dicarboxylic acid.

Hauv lub xeev crystalline, cov molecules oxalic acid tsim ib qho kev npaj tshwj xeeb los ntawm kev sib txuas hydrogen. Kev tshawb fawb X-ray diffraction qhia tau hais tias anhydrous oxalic acid muaj nyob rau hauv ob daim ntawv siv lead ua: α-daim ntawv (rhombic crystals) thiab β-daim ntawv (monoclinic system). Dihydrated oxalic acid tsim ib qho qauv monoclinic, qhov twg cov dej molecules thiab oxalic acid molecules tsim ib lub network hydrogen-bonding nyuaj. Cov yam ntxwv ntawm cov qauv no piav qhia vim li cas oxalic acid crystals poob lawv cov dej ntawm crystallization ua ntej thaum cua sov.

Los ntawm qhov kev pom ntawm cov qauv hluav taws xob, cov pa roj carbon hauv oxalic acid muaj lub xeev oxidation ntawm +3, lub xeev valence nruab nrab. Qhov no muab oxalic acid ob qho tib si qee yam khoom oxidizing thiab cov khoom txo qis tseem ceeb, nrog rau cov khoom txo qis dominating hauv feem ntau cov tshuaj tiv thaiv. Hauv lub molecule, qhov ntev ntawm carbon-carbon bond yog 1.54 Å, qhov sib txuas ob npaug ntawm carbon-oxygen yog 1.20 Å, thiab qhov sib txuas carbon-oxygen ib leeg yog 1.31 Å. Cov ntaub ntawv ntev ntawm bond no qhia txog kev faib tawm electron hauv lub molecule.
