Qhov sib txawv tseem ceeb ntawm kev hloov pauv thiab kev teeb tsa yog qhov kev hloov pauv ntawm tib lub molecule nrawm interconvert whereas lub configurations ntawm tib molecule tsis nkag interconvert.
Ob nqe lus conformation thiab configuration piav qhia txog qhov chaw ntawm ib qho molecule. Peb siv cov ntsiab lus no tseem ceeb hauv cov tshuaj chemical txhawm rau txiav txim siab qhov chaw ntawm cov atoms hauv cov organic tebchaw.
Kev sib haum xeeb yog dab tsi?
Kev sib haum xeeb yog hais txog kev sib txawv ntawm cov atoms hauv cov molecule uas tuaj yeem hloov pauv tau yooj yim. Cov kev hloov pauv no tuaj yeem tshwm sim ntawm chav tsev kub yooj yim. Yog li ntawd, cov qauv no hloov tau yooj yim heev.
Daim duab 01: Kev sib hloov ntawm ob qho kev sib hloov ntawm kev sib hloov
Txawm li cas los xij, cov qauv sib txawv tsis tuaj yeem sib cais ntawm ib leeg. Cov qauv sib txawv no tshwm sim los ntawm kev sib hloov ntawm cov pa roj carbon rau cov pa roj carbon ib leeg (C-C bonds). Xijpeem, peb tuaj yeem tau txais cov qauv sib txawv rau tib lub molecule.
Kev teeb tsa yog dab tsi?
Kev teeb tsa yog hais txog kev sib txawv ntawm cov atoms hauv cov molecule uas tsis tuaj yeem hloov pauv tau yooj yim. Yog li ntawd, cov qauv no tsis hloov pauv. Tsis zoo li conformations, cov qauv no sib cais (peb tuaj yeem cais ib qho kev teeb tsa los ntawm lwm qhov).
Daim duab 02: Cis thiab Trans Configurations ntawm tib molecule.
Yuav kom hloov pauv ib tus qauv mus rau lwm qhov, tej zaum peb yuav tau rhuav tshem cov tshuaj uas twb muaj lawm lossis ua cov tshuaj tshiab ntawm cov atoms. Piv txwv li, cov qauv cis-trans yog txawv configurations.
Dab tsi yog qhov txawv ntawm Kev Hloov Kho thiab Kev Teeb Meem?
Kev sib haum xeeb yog hais txog kev sib txawv ntawm cov atoms hauv ib lub molecule uas tuaj yeem hloov pauv tau yooj yim whereas configuration yog hais txog kev sib txawv ntawm cov atoms hauv cov molecule uas tsis tuaj yeem hloov pauv tau yooj yim. Qhov no yog qhov sib txawv tseem ceeb ntawm conformation thiab configuration. Ntxiv mus, conformations yog inseparable ntawm ib leeg thaum lub configurations ntawm tib molecule yog sib cais. Ntxiv rau qhov ntawd, peb tuaj yeem hloov pauv hloov pauv los ntawm kev hloov cov molecule nyob ib ncig ntawm cov pa roj carbon rau carbon ib daim ntawv cog lus. Peb yuav tsum tau rhuav cov ntawv cog lus uas twb muaj lawm thiab ua cov ntawv cog lus tshuaj tshiab txhawm rau hloov ib qho kev teeb tsa mus rau lwm qhov.
Cov hauv qab no qhia txog qhov sib txawv ntawm kev sib haum xeeb thiab kev teeb tsa hauv daim ntawv tabular.
Summary – Conformation vs Configuration
Kev sib haum xeeb thiab kev teeb tsa piav qhia txog 3D cov qauv ntawm cov tshuaj sib xyaw; feem ntau nyob rau hauv cov organic tebchaw. Txawm hais tias muaj qee qhov sib txawv ntawm ob lub tswv yim no, qhov sib txawv tseem ceeb ntawm kev sib haum xeeb thiab kev teeb tsa; conformations ntawm tib molecule sai interconvert whereas configurations ntawm tib molecule tsis nkag interconvert.
