Muaj ob chav kawm yooj yim ntawm pawg carbonyl: Aldehydes thiab Ketones. Aldehydes muaj cov pa roj carbon atom ntawm pawg carbonyl yog khi rau hydrogen thiab ketones muaj cov pa roj carbon atom ntawm pawg carbonyl yog khi rau ob lwm carbons.
Dab tsi yog ob hom carbonyl pawg?
Carbonyl compounds feem ntau muab faib ua 2 pawg. Ib pawg yog tsim los ntawm aldehydes thiab ketones, lwm qhov muaj cov carboxylic acids thiab lawv cov derivatives. Ob pawg no feem ntau txawv ntawm lawv hom chemistry thiab cov tshuaj tiv thaiv.
Cov pawg carbonyl yog dab tsi?
Ib pawg carbonyl yog ib pawg tshuaj lom neeg ua haujlwm pab pawg tsim los ntawm cov pa roj carbon atom ob npaug rau cov pa atom [C=O] Cov pawg carbonyl yooj yim tshaj plaws yog aldehydes thiab ketones feem ntau txuas rau lwm qhov sib xyaw carbon. Cov qauv no tuaj yeem pom muaj nyob hauv ntau cov tshuaj tsw qab uas ua rau muaj ntxhiab tsw thiab saj.
piv txwv ntawm carbonyl yog dab tsi?
Piv txwv ntawm cov tshuaj carbonyl inorganic yog carbon dioxide thiab carbonyl sulfideIb pawg tshwj xeeb ntawm cov tshuaj carbonyl yog 1, 3-dicarbonyl cov tebchaw uas muaj cov kua qaub hauv cov methylene hauv nruab nrab chav tsev. Piv txwv yog Meldrum's acid, diethyl malonate thiab acetylacetone.
Dab tsi yog aldehydes thiab ketones?
