Kev oxidation ntawm cov cawv thib ob rau ketones yog qhov tseem ceeb oxidation cov tshuaj tiv thaiv hauv cov organic chemistry. Thaum cov cawv thib ob yog oxidized, nws hloov mus rau ketone. Cov hydrogen los ntawm pawg hydroxyl yog ploj nrog rau hydrogen bonded rau lub thib ob carbon.

Ntxiv mus, dab tsi yog qhov khoom ntawm oxidation ntawm thawj cawv?

carboxylic acids

Tom qab ntawd, lo lus nug yog, vim li cas cov cawv thawj thiab theem nrab tuaj yeem oxidized? Cov oxidation ntawm cawv yog ib qho tseem ceeb cov tshuaj tiv thaiv hauv organic chemistry. Thawj cov cawv tuaj yeem ua oxidized tsim aldehydes thiab carboxylic acids; cov cawv thib ob tuaj yeem ua oxidized muab ketones. Tertiary cawv , nyob rau hauv sib piv, tsis tau oxidized tsis rhuav tshem cov molecule C-C bonds.

Kuj paub, qhov twg hauv qab no yog thawj cov khoom oxidation ntawm cov cawv thib ob?

Cov cawv thib ob yog oxidized rau ketones - thiab qhov ntawd yog nws. Piv txwv li, yog tias koj rhaub cov cawv thib ob propan-2-ol nrog sodium los yog poov tshuaj dichromate (VI) tov acidified nrog dilute sulfuric acid, koj tau txais propanone tsim.

PCC puas tuaj yeem oxidize ib qho cawv thib ob?

PCC oxidizes cawv ib rung up oxidation ntaiv, los ntawm thawj cawv mus rau aldehydes thiab los ntawm cawv theem nrab rau ketones. Nyob rau hauv sib piv rau chromic acid, PCC yuav tsis yog oxidize aldehydes rau carboxylic acids.
