Qhov sib txawv tseem ceeb ntawm acyclic thiab cyclic organic tebchaw yog tias acyclic compounds yog cov kab sib txuas, whereas cyclic compounds yog non-linear compounds.
Acyclic thiab cyclic compounds nyob rau hauv cov organic chemistry yog ob yam loj ntawm cov tebchaw uas tau categorized raws li lawv cov qauv tshuaj. Feem ntau acyclic organic tebchaw muaj cyclic isomers. Yog li ntawd, peb lub npe linear lossis acyclic compounds siv lub npe "n-".
YAcyclic Organic Compounds yog dab tsi?
Acyclic organic tebchaw yog cov tshuaj sib txuas uas muaj cov qauv hauv paus. Cov no tseem hu ua open-chain compounds. Cov no yog cov qauv linear es tsis yog cov qauv cyclic. Ntxiv mus, yog tias tsis muaj cov saw hlau txuas nrog rau qhov sib xyaw acyclic, lawv yog cov saw hlau ncaj nraim. Tag nrho cov molecules no yog aliphatic compounds.
Feem ntau cov sib txuas yooj yim hauv cov tshuaj lom neeg, suav nrog alkanes thiab alkenes, muaj ob qho tib si acyclic thiab cyclic isomers. Feem ntau cov qauv cyclic ntawm cov tebchaw no zoo li muaj ntxhiab, muaj cov qauv ruaj khov. Ntxiv mus, nyob rau hauv cov organic tebchaw muaj ntau tshaj plaub carbon atoms ib molecule, lub acyclic molecule feem ntau muaj ncaj-chain los yog branched-chain isomers. Thaum naming cov tebchaw no, peb tuaj yeem siv lub npe "n-" txhawm rau txhawm rau txheeb xyuas cov kab ncaj nraim isomer. E.g. n-butane yog cov saw ncaj-butane molecule.
Daim duab 01: Tus qauv ntawm N-nonane
Ncaj saw molecules tsis ncaj ib txwm vim cov molecules muaj cov ces kaum uas feem ntau tsis yog 180 degrees. Txawm li cas los xij, lo lus linear nyob rau hauv cov ntsiab lus no yog hais txog schematically ncaj molecular qauv. E.g. ncaj-chain alkenes feem ntau muaj wavy lossis "puckered" conformation es tsis yog ib tug ncaj qauv.
Cyclic Organic Compounds yog dab tsi?
Cyclic organic compounds yog cov tshuaj sib txuas uas muaj cov qauv uas tsis yog-linear. Hauv lwm lo lus, cov no yog cov qauv nplhaib. Ib los yog ntau dua series ntawm atoms nyob rau hauv lub compound yog txuas mus rau lub nplhaib qauv.
Daim duab 02: Tsis muaj ntxhiab Cyclic Compounds
Muaj ntau qhov sib txawv ntawm lub nplhaib, nyob ntawm seb muaj pes tsawg tus atoms koom nrog hauv lub nplhaib tsim. Ntxiv mus, muaj cov cyclic organic tebchaw uas tag nrho cov atoms nyob rau hauv lub nplhaib qauv yog carbon atoms thiab lub nplhaib cov qauv uas muaj ob qho tib si carbon thiab lwm yam atoms xws li oxygen thiab nitrogen atoms. Tsis tas li ntawd, cov cyclic compounds tuaj yeem yog aromatic lossis non-aromatic. Aromatic cyclic compounds muaj ib lub nplhaib qauv nrog alternating ib leeg thiab ob/triple bonds, uas ua rau ib tug delocalized pi-electron huab thiab ua rau cov compound unsaturated. Tsis yog-aromatic cyclic compounds, ntawm qhov tod tes, tsuas muaj ib daim ntawv cog lus nkaus xwb lossis ob qho tib si thiab ob npaug / triple daim ntawv cog lus nyob rau hauv cov qauv uas tsis yog hloov pauv.
Qhov txawv ntawm Acyclic thiab Cyclic Organic Compounds yog dab tsi?
Nyob rau hauv cov organic chemistry, cyclic thiab cyclic compounds yog ob pawg tseem ceeb ntawm cov tebchaw uas raug categorized raws li cov qauv ntawm cov molecule. Qhov sib txawv tseem ceeb ntawm acyclic thiab cyclic organic tebchaw yog tias acyclic compounds yog cov kab sib txuas, hos cyclic compounds yog non-linear compounds. Tag nrho cov acyclic organic tebchaw yog cov tsis muaj ntxhiab, tab sis cyclic organic tebchaw tuaj yeem yog cov tshuaj tsw qab lossis tsis muaj ntxhiab.
Hauv qab infographic qhia qhov sib txawv ntawm acyclic thiab cyclic organic compounds nyob rau hauv daim ntawv tabular.
Summary – Acyclic vs Cyclic Organic Compounds
Acyclic thiab cyclic compounds yog ob pawg tseem ceeb ntawm cov tebchaw uas tau categorized raws li cov qauv ntawm cov molecule. Qhov sib txawv tseem ceeb ntawm acyclic thiab cyclic organic compounds yog cov acyclic compounds yog cov kab sib txuas, whereas cyclic compounds yog non-linear compounds.
