Qhov sib txawv tseem ceeb ntawm dextrorotatory thiab levorotatory yog tias dextrorotatory yog hais txog kev sib hloov ntawm lub dav hlau-polarized rau sab xis, whereas levorotatory hais txog kev sib hloov ntawm lub dav hlau-polarized rau sab laug.
Kev sib hloov kho qhov muag yog hais txog kev sib hloov ntawm kev taw qhia ntawm lub dav hlau (ntawm lub teeb) thaum lub teeb dhau los ntawm cov tshuaj lom neeg. Hauv qhov no, cov ntsiab lus dextrorotation thiab levorotation piav qhia txog qhov kev hloov kho qhov muag. Yog li, dextrorotation thiab levorotation yog ob hom kev sib hloov kho qhov muag.
Dextrorotatory yog dab tsi?
Dextrorotatory yog ib lo lus hais txog cov tshuaj sib txuas uas tuaj yeem tig lub dav hlau-polarized lub teeb mus rau sab xis. Dextrorotatory yog lub ntsiab lus ntawm levorotatory, uas yog hais txog kev sib hloov mus rau sab laug. Tsis tas li ntawd, peb tuaj yeem piav qhia txog kev sib hloov dextrorotatory raws li kev sib hloov clockwise ib yam nkaus vim tias kev sib hloov ntawm lub moos yog txoj cai tig. Yog hais tias ib tug compound muaj peev xwm ua tau qhov kev sib hloov no thaum lub dav hlau-polarized lub teeb hla nws, peb hais tias cov khoom yog optically active.
Daim duab 01: Kev sib hloov ntawm lub dav hlau-polarized teeb
Thaum naming dextrorotatory tebchaw, peb yuav tsum tau siv ib tug prefix; Cov ntawv ua ntej tuaj yeem yog "(+)" lossis "d". Ntxiv mus, muaj lwm lo lus tseem ceeb, "kev sib hloov tshwj xeeb" hais txog cov tshuaj sib xyaw no. Kev sib hloov tshwj xeeb piav qhia txog qib uas ib qho chaw yog dextrorotatory lossis levorotatory. Ntawm no, dextrorotatory paub tias muaj kev sib hloov zoo.
Levorotatory yog dab tsi?
Levorotatory yog ib lo lus hais txog cov tshuaj sib txuas uas tuaj yeem tig lub dav hlau-polarized lub teeb mus rau sab laug. Nws yog qhov txawv ntawm lo lus dextrorotatory, uas yog hais txog kev sib hloov mus rau sab laug. Peb tuaj yeem piav qhia txog qhov kev sib hloov no raws li kev sib hloov los tiv thaiv clockwise ib yam nkaus vim tias kev sib hloov los tiv thaiv clockwise yog kev sib hloov ntawm sab laug. Yog hais tias ib tug compound muaj peev xwm ua tau qhov kev sib hloov no thaum lub dav hlau-polarized lub teeb hla nws, peb hais tias cov khoom yog optically active.
Daim duab 02: Levorotatory thiab Dextrorotatory Compounds
Thaum naming levorotatory tebchaw, peb yuav tsum tau siv ib tug prefix; Cov ntawv ua ntej tuaj yeem yog "(-)" lossis "l". Thaum xav txog qhov kev sib hloov tshwj xeeb rau cov levorotatory compounds, lawv paub tias muaj qhov tsis zoo ntawm kev sib hloov.
Qhov txawv ntawm Dextrorotatory thiab Levorotatory yog dab tsi?
Cov ntsiab lus dextrorotatory thiab levorotatory yog qhov muaj txiaj ntsig zoo thaum piav qhia txog kev sib hloov ntawm lub dav hlau-polarized lub teeb los ntawm cov tshuaj sib txawv. Qhov sib txawv tseem ceeb ntawm dextrorotatory thiab levorotatory yog tias dextrorotatory hais txog kev sib hloov ntawm lub dav hlau-polarized lub teeb mus rau sab xis, whereas levorotatory hais txog kev tig ntawm lub dav hlau-polarized rau sab laug. Yog li, cov txheej txheem ntawm qhov kev sib hloov ntawm lub teeb no yog hu ua dextrorotation thiab levorotation. Tsis tas li ntawd, peb tuaj yeem xa mus rau kev sib hloov ntawm lub dav hlau-polarized lub teeb nyob rau hauv lub clockwise kev taw qhia raws li dextrorotary thiab anti-clockwise rotation yog levorotatory.
Thaum naming cov tebchaw, peb yuav tsum tau siv prefixes. Rau cov tebchaw dextrorotary, muaj ob lub npe uas peb tuaj yeem siv tau: "(+)" lossis "d". Ib yam li ntawd, rau levorotatory tebchaw, cov lus ua ntej peb siv tau yog "(-)" lossis "l". Tsis tas li ntawd, muaj lwm lo lus tseem ceeb, "kev sib hloov tshwj xeeb" hais txog cov tshuaj sib xyaw no. Qhov tshwj xeeb kev sib hloov rau dextrorotary tebchaw yog hais tias yuav zoo thaum rau levorotatory tebchaw, nws yog tsis zoo.
Hauv qab infographic tabulates qhov sib txawv ntawm dextrorotatory thiab levorotatory.
Summary – Dextrorotatory vs Levorotatory
Cov ntsiab lus dextrorotatory thiab levorotatory yog qhov muaj txiaj ntsig zoo thaum piav qhia txog kev sib hloov ntawm lub dav hlau-polarized lub teeb los ntawm cov tshuaj sib txawv. Qhov sib txawv tseem ceeb ntawm dextrorotatory thiab levorotatory yog tias dextrorotatory hais txog kev sib hloov ntawm lub dav hlau-polarized lub teeb mus rau sab xis, whereas levorotatory hais txog kev tig ntawm lub dav hlau-polarized rau sab laug. Cov txheej txheem ntawm qhov kev sib hloov ntawm lub teeb no yog hu ua dextrorotation thiab levorotation.
