Qhov sib txawv tseem ceeb ntawm homonuclear thiab heteronuclear aromatic compounds yog tias homonuclear aromatic compounds muaj atoms ntawm tib cov tshuaj nyob rau hauv lub nplhaib qauv whereas lub heteronuclear aromatic tebchaw muaj atoms ntawm cov tshuaj sib txawv nyob rau hauv lub nplhaib qauv.
Homonuclear thiab heteronuclear aromatic compounds yog cov organic tebchaw uas muaj cov qauv nplhaib. Thiab, cov qauv nplhaib no muaj cov atoms zoo tib yam lossis txawv atoms. Yog li ntawd, lawv muaj cov tshuaj lom neeg thiab lub cev sib txawv nyob ntawm seb hom atoms hauv cov qauv ntawm lub nplhaib.
Homonuclear Aromatic Compounds yog dab tsi?
Homonuclear aromatic compounds yog cov khoom tsim los ntawm cov atoms ntawm tib cov tshuaj lom neeg sib koom ua ke ntawm covalent bonds los tsim ib lub nplhaib qauv. Feem ntau homonuclear aromatic compounds muaj carbon atoms uas ua rau lub nplhaib. Muaj ob qho tib si los yog ob daim ntawv cog lus ntawm cov atoms no, thiab tuaj yeem muaj hydrogen lossis lwm cov atoms (los yog pawg atoms) txuas rau cov pa roj carbon atoms ua pawg pendant.
Daim duab 1: Benzene yog Homonuclear Aromatic Compound
Benzene yog homonuclear aromatic compound uas muaj rau carbon atoms nyob rau hauv ib lub nplhaib txuas los ntawm alternating ib thiab ob daim ntawv cog lus ntawm lawv. Tsis tas li ntawd, cov tebchaw no ua tiav cov kev xav tau ntawm cov qauv aromatic; lawv muaj ib tug conjugated pi-electron system, planar, electron delocalization, alternating ib leeg thiab ob daim ntawv cog lus, thiab lwm yam.
Dab tsi yog Heteronuclear Aromatic Compounds?
Heteronuclear aromatic compounds yog cov khoom tsim los ntawm cov atoms ntawm cov tshuaj sib txawv sib koom ua ke ntawm covalent bonds los tsim lub nplhaib qauv. Raws li qhov yuav tsum tau ua ib qho chaw muaj ntxhiab, heteronuclear aromatic compounds muaj pi-electron system, alternating ib leeg thiab ob daim ntawv cog lus, delocalized electron system, thiab lwm yam.
Daim duab 2: Furan muaj Carbon Atoms thiab Oxygen Atom nyob rau hauv lub nplhaib qauv
Feem ntau, cov tebchaw no feem ntau muaj carbon atoms nrog rau lwm cov atoms xws li nitrogen, sulfur, thiab oxygen. Piv txwv li, pyridine muaj cov qauv uas zoo ib yam li benzene, tab sis muaj nitrogen atom es tsis txhob carbon atom nyob rau hauv lub nplhaib qauv. Ib yam li ntawd, furan muaj plaub carbon atoms thiab ib qho oxygen atom, ua rau nws lub nplhaib qauv.
Qhov txawv ntawm Homonuclear thiab Heteronuclear Aromatic Compounds yog dab tsi?
Homonuclear thiab heteronuclear aromatic compounds yog cov organic tebchaw uas muaj cov qauv nplhaib. Qhov sib txawv tseem ceeb ntawm homonuclear thiab heteronuclear aromatic tebchaw yog tias homonuclear aromatic tebchaw yog tsim los ntawm cov atoms ntawm tib yam tshuaj lom neeg sib koom ua ke ntawm covalent bonds los tsim ib lub nplhaib qauv whereas lub heteronuclear aromatic tebchaw muaj atoms ntawm cov tshuaj sib txawv nyob rau hauv lub nplhaib. structure.
Ntxiv mus, homonuclear aromatic compounds muaj cov tshuaj tsis muaj zog thaum lub heteronuclear aromatic compounds muaj ob qho tib si polar thiab nonpolar chemical bonds. Benzene yog ib qho piv txwv ntawm homonuclear aromatic compound thaum pyridine thiab furan yog piv txwv ntawm heteronuclear aromatic compounds.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm homonuclear thiab heteronuclear aromatic compounds.
Summary – Homonuclear vs Heteronuclear Aromatic Compounds
Homonuclear thiab heteronuclear aromatic compounds yog cov organic tebchaw uas muaj cov qauv nplhaib. Cov qauv nplhaib no muaj cov atom zoo tib yam lossis txawv atoms. Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm homonuclear thiab heteronuclear aromatic compounds yog tias homonuclear aromatic compounds muaj atoms ntawm tib cov tshuaj nyob rau hauv lub nplhaib qauv whereas lub heteronuclear aromatic tebchaw muaj atoms ntawm cov tshuaj sib txawv nyob rau hauv lub nplhaib qauv.
