Qhov Tseem Ceeb Qhov txawv - Alicyclic vs Aromatic Compounds
Raws li qhov xwm txheej ntawm cov pob txha pob txha, cov organic tebchaw tau muab faib ua plaub pawg xws li, a) aliphatic b) alicyclic, c) aromatic, thiab d) heterocyclic compounds. aliphatic tebchaw muaj ib los yog ntau cov pa roj carbon bonds tab sis tsis muaj cov qauv cyclic. Alicyclic compounds yog tsim los ntawm kev koom nrog ob lub pa roj carbon atoms ntawm ib qho aliphatic saw los ntawm covalent daim ntawv cog lus ua rau cov qauv cyclic. Cov tshuaj tsw qab kuj yog cyclic, tab sis cov ntawv cog lus yog delocalized. Heterocyclic compounds tuaj yeem yog alicyclic lossis aromatic, tab sis lub nplhaib muaj ib lossis ntau dua hetero atoms. Kab lus no tsom mus rau qhov sib txawv ntawm alicyclic thiab aromatic compounds. Qhov sib txawv tseem ceeb ntawm alicyclic thiab aromatic compounds yog tias alicyclic tebchaw yog cyclic compounds tsis tau zoo li cov aliphatic tebchaw nyob rau hauv lawv cov khoom, whereas aromatic tebchaw muaj conjugated rings thiab qhia aromaticity raws li cov khoom tseem ceeb. Tsis tas li ntawd, muaj ntau qhov sib txawv uas muaj nyob nruab nrab ntawm ob pawg sib txuas thiab lawv tau tham hauv qab no.
Alicyclic Compounds yog dab tsi?
Alicyclic compounds yog cov organic tebchaw uas muaj cov nplhaib kaw ntawm carbon atoms. Cov tebchaw no yog tsim los ntawm kev koom nrog ob lub pa roj carbon atom ntawm ib qho aliphatic saw los ntawm covalent daim ntawv cog lus. Li no, cov khoom ntawm alicyclic compounds zoo ib yam li cov khoom ntawm aliphatic compounds.
Alicyclic compounds kuj hu ua cycloaliphatic compounds. Cov tshuaj no yuav saturated los yog unsaturated. Vim yog ringed-structure, aliphatic tebchaw qhia stereochemical zog. Txawm li cas los xij, cov khoom no tsis muaj nyob hauv aliphatic compounds.
Daim duab 01: Cyclopropane
Qee yam tseem ceeb hauv ntuj xws li steroids, terpenoids, thiab ntau alkaloids muaj alicyclic compounds. Cyclopropane thiab cyclohexane yog cov yooj yim alicyclic compounds.
Aromatic Compounds yog dab tsi?
Aromatic compounds yog cov organic compounds nrog conjugated rings. Muab ob npaug rau thiab ib daim ntawv cog lus tau hloov pauv los tsim cov qauv cyclic. Benzene yog qhov yooj yim tshaj plaws aromatic compound ntawm cov tshuaj formula C6H6 Vim yog cov delocalized bonds thiab conjugated ringed-structure, aromatic compounds nthuav tawm cov khoom (aromaticity) uas txawv ntawm aliphatic thiab alicyclic compounds.
Muaj qee yam tseem ceeb ntawm cov tshuaj tsw qab vim lawv cov aromaticity. Raws li cov tshuaj formula, aromatic compounds qhia ib tug high degree ntawm unsaturation. Txawm li cas los xij, cov tebchaw no tsis tshua muaj kev cuam tshuam ntxiv tsis zoo li lawv cov khoom sib txuas tsis txaus ntseeg aliphatic thiab lawv xav tau kev hloov pauv. Cov molecules ntawm aromatic tebchaw yog ntau thermodynamically ruaj khov raws li lawv qhia tsis tshua muaj cua sov ntawm combustion thiab hydrogenation. Raws li X-ray thiab electron diffraction txoj kev, cov molecules ntawm aromatic compounds yog tiaj.
Daim duab 02: Benzene
Lub npe 'aromatic' tshwm sim los ntawm Greek lo lus aroma, txhais tau tias tsw qab ntxiag, yog siv rau cov tebchaw vim tias feem ntau ntawm cov tebchaw no muaj ntxhiab tsw qab. Qee qhov piv txwv ntawm cov tshuaj tsw qab muaj xws li phenol, naphthalene, anthracene thiab lwm yam.

Summary – Alicyclic vs Aromatic Compounds
Alicyclic thiab aromatic compounds yog ob pawg ntawm cyclic organic tebchaw uas qhia txog cov khoom sib txawv. Alicyclic compounds yog tsim los ntawm aliphatic compounds, yog li muaj cov khoom zoo ib yam li aliphatic compounds. Aromatic tebchaw muaj conjugated rings uas qhia aromaticity. Aliphatic tebchaw tej zaum yuav saturated los yog unsaturated, whereas aromatic compounds yog unsaturated thiab muaj ob thiab ib daim ntawv cog lus sib hloov nyob rau hauv lub nplhaib. Qhov no yog qhov txawv ntawm alicyclic thiab aromatic compounds.
