Cov molecules no muaj dav hlau ntawm symmetry(lub dav hlau ntsug mus hla cov kab liab tawg perpendicular rau lub dav hlau ntawm lub nplhaib) thiab, yog li ntawd, yog achiral, tab sis muaj ob lub chaw chiral.
Pob enantiomers muaj lub dav hlau sib luag?
Muaj ob hom stereoisomers: enantiomers thiab diastereomers. Enantiomers yog khub ntawm stereoisomers uas yog daim iav duab ntawm ib leeg: yog li, A thiab B yog enantiomers. … Txawm li cas los xij, nws yog superimposable ntawm nws daim iav duab, thiab muaj lub dav hlau sib luag. Cov molecule no yog achiral (tsis muaj chirality).
Puas yog diastereomers iav duab?
Diasteemers yog stereoisomers uas tsis cuam tshuam li khoom thiab daim iav duabthiab tsis yog enantiomers. Tsis zoo li enatiomers uas yog daim iav duab ntawm ib leeg thiab tsis-sumperimposable, diastereomers tsis yog iav dluab ntawm ib leeg thiab tsis-superimposable.
Cov neeg mob ntshav qab zib puas muaj Stereocenters?
Stereoisomers yuav tsum tsis muaj stereocenters: E thiab Z alkenes yog cov piv txwv zoo ntawm diastereomers. Tseem muaj cov chav kawm ntawm cov molecules uas yog chiral tab sis tsis muaj stereocenters (peb yuav tsis quav ntsej cov no).
tus piv txwv diastereomers yog dab tsi?
Cov tebchaw uas muaj tib daim ntawv cog lus ntawm ib lub stereocenter tab sis txawv kev teeb tsa ntawm lwm lub stereocenter hu ua Diastereomers. Piv txwv li xav txog ob lub tebchaw nrog rau lub nplhaib rau tus tswvcuab uas muaj ob qhov hloov pauv txhua, chlorine atom thiab ib pawg ethyl, cov tshuaj no yog Diastereomers.
