Yuav ua li cas cov organic compound muaj ib pawg hydroxyl functional?
Alcohols yog cov organic tebchaw uas cov pab pawg hydroxyl ua haujlwm (-OH) raug khi rau carbon atom. Cawv yog ib chav kawm tseem ceeb ntawm cov molecules nrog ntau yam kev tshawb fawb, kev kho mob, thiab kev lag luam.
Dab tsi yog pab pawg ua haujlwm ntawm ketone?
In chemistry, a ketone /ˈkiːtoʊn/ is a functional group nrog covqauv R2C=O , qhov twg R tuaj yeem ua ntau yam sib txawv ntawm cov pa roj carbon. Ketones muaj cov pab pawg carbonyl (carbon-oxygen ob daim ntawv cog lus). Qhov yooj yim tshaj plaws ketone yog acetone (R=R'=methyl), nrog rau cov mis CH3C(O)CH3.
