Qhov Tseem Ceeb Qhov txawv - Aryl vs Phenyl
Aryl thiab Phenyl yog ob lub tebchaw organic uas muaj ib lossis ntau lub nplhaib uas muaj ntxhiab tsw qab txawm tias muaj qhov sib txawv ntawm lawv li Phenyl yog ib pawg ntawm tsev neeg aryl. Phenyl tseem tuaj yeem suav hais tias yog tus tswv cuab yooj yim ntawm pawg aryl. Qhov sib txawv tseem ceeb ntawm pawg phenyl thiab lwm pawg aryl yog tias Phenyl compounds yog derivatives ntawm benzene thaum aryl compounds tuaj yeem yog cov derivatives ntawm phenyl, naphthyl, xylyl lossis thienyl.
Tag nrho cov tebchaw no muaj tsawg kawg yog ib lub nplhaib tsis muaj carbocyclic uas muaj rau Carbon atoms; Txhua cov pa roj carbon atom koom rau ob lwm Carbon atom los ntawm ib daim ntawv cog lus thiab ib daim ntawv cog lus ob (-C=C-C); tsim ib lub nplhaib qauv ntawm unsaturated Carbon system.
Yuav ua li cas yog Aryl Compounds?
Aryl compounds yog cov organic molecules uas muaj lub nplhaib uas muaj ntxhiab. Lawv tuaj yeem muaj lwm pawg ua haujlwm lossis lwm yam khoom siv xws li phenyl (benzene), naphthyl (naphthalene), tolyl lossis xylyl compounds. Cov cuab yeej tseem ceeb ntawm aryl tebchaw yog muaj ib lossis ntau lub nplhaib ntawm Carbon atoms nrog kev sib hloov ib leeg thiab ob daim ntawv cog lus hauv lawv cov qauv tshuaj. Lub nplhaib kaw lus tau hais tias tsis txaus ntseeg vim yog delocalized pi-electron system.
YPhenyl Compounds yog dab tsi?
Cov organic molecules hauv phenyl pawg muaj cov qauv cyclic nrog cov qauv molecular C6H5; tus qauv cyclic no muaj cov qauv zoo ib yam li benzene nplhaib tsis muaj Hydrogen atom. Lub hydrogen atom nyob rau hauv lub nplhaib benzene yog hloov los ntawm lwm yam tshuaj. Muaj ob qho tib si ntuj thiab hluavtaws sib txuas hauv phenyl pawg. Qee cov khoom siv hluavtaws feem ntau pom muaj nyob rau hauv kev lag luam polymer. Hauv qee cov phenyl tebchaw, muaj ntau tshaj ib pawg benzyl hauv cov qauv.
Toluene muaj ib pawg phenyl, tab sis Triphenylmethane muaj peb pawg phenyl.
Qhov txawv ntawm Aryl thiab Phenyl yog dab tsi?
Definition of Aryl thiab Phenyl
Aryl Compounds: Aryl compounds muaj lub nplhaib uas muaj ntxhiab nrog ib lossis ntau pawg ua haujlwm lossis cov khoom siv hloov pauv. Lub nplhaib uas muaj ntxhiab tuaj yeem yog phenyl, naphthyl, tolyl lossis xylyl pawg.
Aromatic nplhaib: Organic hydrocarbon molecules uas muaj benzene los yog lwm yam qauv ntawm lub nplhaib.
Phenyl Compounds: Phenyl pawg yog ib tug tswv cuab ntawm pawg aryl. Nws muaj cov organic molecules muab tau los ntawm benzene. Hauv lwm lo lus, phenyl tebchaw yog tsim los ntawm kev hloov ib qho ntawm Hydrogen atoms hauv lub nplhaib benzene los ntawm lwm hom tshuaj.
Khoom ntawm Aryl thiab Phenyl
Examples
Aryl Compounds:
| Aryl pawg | |
| Phenyl pawg – C6H5 | Tau los ntawm benzene |
| xylyl group – (CH3)2C6H 3 | YDrived los ntawm xylene |
| tolyl group – CH3C6H4 | Tau los ntawm toluene |
| naphthyl – C10H7 | Drived los ntawm naphthalene |
Phenyl Compounds: Hauv phenyl tebchaw, lub nplhaib uas muaj ntxhiab muaj cov qauv zoo ib yam li hauv benzene nrog ib qho Hydrogen atom tau tshem tawm ntawm lub nplhaib. Piv txwv li: (Phenol, Toluene, Amino acid phenylalanine)
Ring System
Aryl Compounds: Hauv aryl compounds, lub nplhaib kaw tuaj yeem yog homocyclic (ib lub nplhaib system) lossis polycyclic. Cov rings polycyclic tuaj yeem muaj cov qauv nplhaib txuas rau ib leeg.
Phenyl Cov Cheeb Tsam: Hauv cov tshuaj phenyl, lawv tsuas muaj lub nplhaib monocyclic; Tag nrho cov nplhaib no yog ib qho derivative ntawm benzene (-C6H5). Lawv tsis muaj macrocyclic lossis polycyclic rings.
