Acyl pawg thiab pawg alkyl ob qho tib si muaj cov khoom uas tsuas yog ua los ntawm carbons thiab hydrogens. Tab sis tsuas yog acyl pawg muaj carbonyl pab pawg ua los ntawm cov pa roj carbon ob npaug rau cov pa oxygen. Ib acyl pawg muaj oxygen atom, thaum lub pawg alkyl tsis.

Tom qab ntawd, dab tsi yog txhais los ntawm acyl pawg?

Ib pawg acyl yog moiety muab los ntawm kev tshem tawm ntawm ib lossis ntau dua hydroxyl pab pawg los ntawm oxoacid, nrog rau cov inorganic acids. Nws muaj ob-bonded oxygen atom thiab alkyl pab pawg (R-C = O). Hauv cov organic chemistry, lub pawg acyl (IUPAC lub npe: alkanoyl) feem ntau yog muab los ntawm carboxylic acid.

Ib yam li ntawd, dab tsi yog ib pawg alkyl hauv organic chemistry? Alkyl pawg . Definition: Ib alkyl yog ib tug functional pab pawg ntawm ib organic tshuaj uas tsuas muaj carbon thiab hydrogen atoms, uas yog teem nyob rau hauv ib tug saw. Lawv muaj cov qauv dav dav C H2 ib n+1. Piv txwv xws li methyl CH3 (los ntawm methane) thiab butyl C2H5 (ua los ntawm butane).

Kuj tseem paub yog, qhov txawv ntawm alkyl thiab acyl yog dab tsi?

Alkyl thiab acyl tuaj yeem ua raws li pawg ua haujlwm ntawm lub ntsiab molecule. Tus yuam sij Qhov sib txawv ntawm alkyl thiab acyl pawg yog li ntawd acyl ua pab pawg muaj ib qho oxygen atom txuas nrog a ob daim ntawv cog lus rau carbon atom whereas alkyl pawg tsis muaj oxygen atom txuas rau nws cov pa roj carbon atoms.

Dab tsi yog qhov txawv ntawm pawg carbonyl thiab pawg acyl?

Lesson Summary Lub carbonyl pawg yog cov pa roj carbon ob npaug rau cov pa oxygen, ib acyl pawg ntxiv cov lus piav qhia ntxiv nrog rau cov pa roj carbon monoxide rau ib qho ntawm R pab pawg nrog rau carbon-oxygen ob daim ntawv cog lus.
