Enantiomers yog chiral molecules uas yog daim iav duab ntawm ib leeg. Tsis tas li ntawd, cov molecules yog non-superimposable ntawm ib leeg. Qhov no txhais tau hais tias cov molecules tsis tuaj yeem muab tso rau saum ib leeg thiab muab tib lub molecule. Nws yog qee zaum nyuaj los txiav txim siab seb puas yog ob lub molecules yog cov enantiomers.

Tom qab ntawd, qhov txawv ntawm tus enantiomer thiab diastereomer yog dab tsi?

Muaj ob hom stereoisomers- cov enantiomers thiab cov neeg txom nyem . Enantiomers muaj cov chaw chiral uas yog daim iav duab thiab tsis yog superimposable. Cov neeg txom nyem muaj cov chaw chiral uas tsis yog superimposable tab sis tsis yog daim iav duab. Muaj peev xwm muaj ntau tshaj 2 nyob ntawm seb muaj pes tsawg tus stereocenters.

Tsis tas li ntawd, Stereocenter organic chemistry yog dab tsi? Stereocenter (chiral center): Ib qho atom nrog peb lossis ntau qhov sib txawv, kev sib hloov ntawm ob ntawm cov ntawv txuas no ua rau lwm tus stereoisomer. Feem ntau, tab sis tsis txwv rau, ib qho sp3 (tetrahedral) carbon atom bearing plaub yam sib txawv.

Ib yam li ntawd, nws yog nug, dab tsi yog cov piv txwv ntawm enantiomers?

Daim duab 2.3D. 1: Enantiomers D-alanine thiab L-alanine yog piv txwv ntawm enantiomers los yog iav duab. Tsuas yog L-forms ntawm amino acids yog siv los ua cov proteins. Organic compounds uas muaj chiral carbon feem ntau muaj ob lub qauv uas tsis yog superposable.

Mesomers yog dab tsi?

mesomers yog ib hom kev sib txuas uas qhov sib hloov ntawm lub dav hlau polarized yog xoom. i.e yuav yooj yim, mesomers yog hom organic tebchaw uas muaj ob chiral carbons tam sim no thiab cov ob zoo sib xws, yog li net rotation yog xoom. Meso compound yog ib qho achiral compound uas muaj chiral chaw.
