Ketones . A ketone lub cev yog ib tug compound uas muaj ib pawg carbonyl nrog ob pawg hydrocarbon txuas rau nws. Ob qhov yooj yim tshaj plaws yog propanone , ua lag luam nyob rau hauv lub npe acetone, thiab 2-butanone, ua lag luam nyob rau hauv lub npe methyl ethyl ketone lub cev lub MEK.
Ntawm no, propanone puas yog aldehyde lossis ketone?
Feem ntau Aldehydes thiab Ketones Acetaldehyde (ethanal) yog cov kua tsis muaj xim, flammable, C2H4O, siv los tsim acetic acid, naj hoom, thiab tshuaj. Kuj hu ua aldehyde . Acetone ( propanone ) yog cov kua tsis muaj xim, tsis muaj zog, tsis tshua muaj hluav taws kub ketone lub cev , CH3COCH3, dav siv los ua cov kuab tshuaj organic.
Tsis tas li ntawd, vim li cas propanone yog thawj tus tswv cuab ntawm ketone? Txij li thaum methanone tsuas muaj 1 carbon atom - tsis muaj cov compound no, cov ua ntej compound nrog ib tug susbstitued ketone lub cev pawg yog li ntawd propanone . ketone lub cev yuav tsum muaj tsawg kawg peb carbon atoms nyob rau hauv nws molecule, ib tug carbon atom ntawm lub ketone lub cev pawg thiab ob carbon atom ntawm nws ob sab.
Kuj nug, vim li cas propanone Qhov yooj yim tshaj plaws ketone?
Vim tias pawg carbonyl hauv a ketone lub cev yuav tsum tau txuas nrog ob pawg carbon, lub yooj yim tshaj plaws ketone muaj peb carbon atoms. Nws yog dav paub tias yog acetone, ib lub npe tshwj xeeb uas tsis cuam tshuam nrog lwm cov npe rau ketones . Thawj tus tswv cuab ntawm Ketones yog (IUPAC lub npe) 2 - propanone . Qhov no tseem hu ua Acetone.
Puas yog propanone soluble hauv dej?
Solubility hauv dej Piv txwv li, methanal, ethanal thiab propanone - qhov me me aldehydes thiab ketones - yog miscible nrog dej nyob rau hauv txhua proportions. Yog vim li cas rau lub solubility yog hais tias txawm aldehydes thiab ketones tsis tuaj yeem hydrogen daim ntawv cog lus nrog lawv tus kheej, lawv muaj peev xwm hydrogen bond nrog dej molecules.

Koj paub qhov txawv ntawm aldehyde los ntawm ketone li cas?
Koj yuav nco ntsoov tias qhov sib txawv ntawm aldehyde thiab ketone yog qhov muaj hydrogen atom txuas rau carbon-oxygen ob daim ntawv cog lus hauv aldehyde. Ketones tsis muaj hydrogen. Lub xub ntiag ntawm hydrogen atom ua rau aldehydes yooj yim heev rau oxidize (piv txwv li, lawv muaj zog txo cov neeg ua haujlwm)
Puas yog kev poob ntawm kev puas tsuaj yog kev siv nyiaj?
Ib qho kev poob qis ua rau nws mus rau hauv 'tag nrho cov nuj nqis khiav haujlwm' ntawm daim ntawv qhia nyiaj tau los thiab, yog li, txo cov nyiaj tau los ntawm tuam txhab
Puas yog lub hauv paus ntiag tug puas yog pej xeem kev siab hlub?
Lub hauv paus ntiag tug yog ib lub koom haum uas tsis muaj txiaj ntsig uas feem ntau tsim los ntawm ib tus neeg txais txiaj ntsig, feem ntau yog ib tus neeg lossis lag luam. Ib qho kev siab hlub rau pej xeem, piv txwv li, nyiam ua qee yam kev ua haujlwm ncaj qha, xws li kev ua haujlwm tsis muaj tsev nyob
Dab tsi yog aldehyde thiab ketone?
Aldehydes muab lawv lub npe los ntawm lub cev qhuav dej ntawm cawv. Aldehydes muaj cov pab pawg carbonyl sib txuas nrog tsawg kawg ib lub atom hydrogen. Ketones muaj cov pab pawg carbonyl txuas rau ob lub atoms. Aldehydes thiab ketones yog cov organic tebchaw uas suav nrog cov pab pawg ua haujlwm carbonyl, C = O
Dab tsi yog qhov txawv ntawm aldehyde ib ketone thiab carboxylic acid?
Aldehydes thiab ketones muaj cov pab pawg ua haujlwm carbonyl. Nyob rau hauv ib qho aldehyde, carbonyl yog nyob rau hauv qhov kawg ntawm ib tug carbon saw, thaum nyob rau hauv ib tug ketone, nws yog nyob rau hauv nruab nrab. Carboxylic acid muaj cov carboxyl functional pawg
