Nyob rau hauv cov organic chemistry, ib pawg carbonyl yog ib pab pawg ua haujlwm tsim los ntawm cov pa roj carbon atom ob npaug rau ib qho oxygen atom: C=O. Nws yog ib qho ntawm ob peb chav kawm ntawm cov organic tebchaw, ua ib feem ntawm ntau pawg ua haujlwm loj. Ib qho chaw uas muaj cov pab pawg carbonyl feem ntau hu ua carbonyl compound.
Pab twg muaj pawg carbonyl?
Aldehydes thiab ketones muaj cov pawg carbonyl txuas rau alkyl lossis aryl pawg thiab hydrogen atom lossis ob qho tib si. Cov pab pawg no muaj kev cuam tshuam me ntsis ntawm cov khoom siv hluav taws xob hauv cov pa carbonyl; Yog li, cov khoom ntawm aldehydes thiab ketones raug txiav txim los ntawm tus cwj pwm ntawm pawg carbonyl.
Koj txheeb xyuas pawg carbonyl li cas?
