Cov tshuaj formula uas sawv cev rau ib qho aldehyde yog C2H4O C2H4O Thaum nqa los ntawm lub cev, acetaldehyde yog metabolized sai hauv daim siab rau acetic acid. Tsuas yog ib feem me me yog exhaled tsis hloov. Tom qab txhaj tshuaj, ib nrab-lub neej hauv cov ntshav yog kwv yees li 90 vib nas this. https://en.wikipedia.org › wiki › Acetaldehyde
Acetaldehyde - Wikipedia
. Lo lus teb yog tsab ntawv C.
Puas yog piv txwv ntawm aldehyde?
Aldehydes tau muab tib lub npe tab sis nrog lub ntsiab lus -ic acid hloov los ntawm -aldehyde. Ob qho piv txwv yog formaldehyde thiab benzaldehyde . Raws li lwm qhov piv txwv, lub npe ntawm CH2=CHCHO, uas lub npe IUPAC yog 2-propenal, yog acrolein, lub npe muab los ntawm acrylic acid, niam txiv carboxylic acid.
Aldehyde functional pawg yog dab tsi?
Tshuaj, ib qho aldehyde /ˈældɪhaɪd/ yog ib qho chaw uas muaj ua haujlwm pab pawg nrog cov qauv -CHO, suav nrog lub chaw carbonyl (cov pa roj carbon ob npaug rau oxygen) nrog cov pa roj carbon atom kuj txuas rau hydrogen thiab rau ib qho generic alkyl lossis sab saw R pawg.
Cov mis ntawm aldehyde yog dab tsi?
Nyob hauv aldehydes, pawg carbonyl muaj ib lub atom hydrogen txuas rau nws ua ke nrog 2nd hydrogen atom lossis hydrogen pawg uas tej zaum yuav yog ib pawg alkyl lossis ib qho uas muaj lub nplhaib benzene. Cov mis mos ntawm alkene yog C H2 +1 yog li cov qauv dav dav rau aldehyde yuav yog C H2 +1CHO or C H2nO.
Amide formula yog dab tsi?
6.9 Amides
Cov amides yooj yim tshaj plaws yog cov derivatives ntawm ammonia (NH3) uas ib lub atom hydrogen tau hloov los ntawm pawg acyl. Kev sib raug zoo thiab ntau ntau yog amides muab los ntawm thawj amines (R′NH2) nrog cov mis RC(O)NHR′.
