aldehyde, ib chav kawm ntawm cov organic tebchaw uas cov pa roj carbon atom sib koom ob daim ntawv cog lus nrog oxygen atom, ib daim ntawv cog lus nrog hydrogen atom, thiab ib daim ntawv cog lus. nrog rau lwm atom los yog pab pawg ntawm atoms (tsim R hauv cov qauv tshuaj thiab cov qauv duab).
Koj paub li cas pab pawg aldehyde?
Ib qho aldehyde muaj tsawg kawg ib qho hydrogen txuas nrog carbonyl carbon. Cov pab pawg thib ob yog ib pawg hydrogen lossis carbon-based. Hauv qhov sib piv, ketone muaj ob pawg carbon-based txuas nrog carbonyl carbon.
pawg ketone yog dab tsi?
In chemistry, a ketone /ˈkiːtoʊn/ is a pab pawg ua haujlwm nrog cov qauv R2C=O, qhov twg R tuaj yeem ua tau ntau yam khoom uas muaj cov pa roj carbon. Ketones muaj cov pab pawg carbonyl (carbon-oxygen ob daim ntawv cog lus). … Ntau ketones tseem ceeb heev hauv biology thiab hauv kev lag luam.
Nws yog ib pab pawg ua haujlwm hu ua aldehyde?
Aldehydes thiab ketones yog cov organic tebchaw uas suav nrog a carbonyl functional pawg, C=O. Cov pa roj carbon atom ntawm pab pawg no muaj ob daim ntawv cog lus ntxiv uas yuav tau nyob los ntawm hydrogen lossis alkyl lossis aryl hloov pauv. Yog tias tsawg kawg ib qho ntawm cov khoom siv no yog hydrogen, qhov sib xyaw yog aldehyde.
YPuas yog cawv yog aldehyde?
Ib cawv nrog nws -OH pawg sib koom ua ke rau cov pa roj carbon atom uas tau sib koom ua ke tsis muaj lossis lwm cov pa roj carbon atom yuav tsim ib qho aldehyde. Ib qho cawv nrog nws-OH pab pawg txuas nrog ob lwm carbon atoms yuav tsim ib ketone.
