Nyob rau hauv lub ntsiab lus, chiral molecules tig rau hauv ib qho kev taw qhia tshwj xeeb (R lossis S) thaum achiral molecules yuav tig rau ob qho tib si. Cov kev sib hloov yuav thim ib leeg tawm, ua rau lawv tsis ua haujlwm optically.
Puas yog achiral molecules optically tsis ua haujlwm?
Tag nrho cov ntshiab achiral compounds yog optically inactive. Piv txwv li: Chloroethane (1) yog achiral thiab tsis tig lub dav hlau ntawm lub dav hlau-polarized lub teeb. Yog li, 1 yog optically inactive.
txhais li cas rau qhov tsis ua haujlwm kho qhov muag?
Optically inactive: Ib yam khoom uas tsis muaj kev ua haujlwm kho qhov muag, piv txwv li, ib yam khoom uas tsis tig lub dav hlau ntawm lub dav hlau polarized teeb.
Vim li cas qee cov molecules optically tsis ua haujlwm?
Thaum lub molecule yog achiral! Yog hais tias ib lub teb tsis tig lub dav hlau polarized lub teeb, nws yog optically inactive. Nyob rau hauv rooj plaub uas tus qauv hauv (5) ib daim duab saum toj no yog meso lossis achiral nyob rau hauv lwm txoj kev, cov molecule tau hais tias yog optically inactive.
Puas achiral compounds muaj kev ua haujlwm kho qhov muag?
Cov kev daws teeb meem ntawm chiral compounds muaj cov cuab yeej ntawm rotating dav hlau-polarized lub teeb dhau los ntawm lawv. … Achiral compounds tsis muaj cov cuab yeej no Lub peev xwm ntawm kev daws teeb meem tig dav hlau-polarized lub teeb hauv qhov kev zam no yog hu ua kev ua haujlwm kho qhov muag, thiab cov kev daws teeb meem uas muaj peev xwm tau hais tias ua haujlwm kho qhov muag.
