Diastereomers txhais tau tias tsis yog daim iav duab tsis zoo ib yam stereoisomers. … Ntau tus isomers conformational yog diastereomers thiab. Diastereoselectivity yog qhov kev nyiam rau kev tsim ntawm ib lossis ntau tshaj ib tus diastereomer tshaj lwm tus hauv cov tshuaj tiv thaiv organic.
Puas yog diastereomer yog kev teeb tsa isomer?
Diastereomers Yog Stereoisomers Tsis yog Enantiomers Yog li yog (2R, 3R)-tartaric acid thiab (2S, 3S)-tartaric acid yog enantiomers, yuav ua li cas Peb puas piav txog kev sib raug zoo ntawm txhua qhov ntawm cov molecules thiab meso-tartaric acid? Nyob rau hauv cov organic chemistry, peb hu ua "stereoisomers uas tsis yog enantiomers", diastereomers.
Cov neeg mob ntshav qab zib puas tuaj yeem yog tus qauv isomers?
kab lis kev cai isomers (kev sib txuas sib txawv) piv rau stereoisomers (kev sib txawv hauv qhov chaw) enantiomers (stereoisomers uas tsis yog cov duab iav superimposable) piv rau cov duab diastereomers (stereoisomers uas tsis yog cov duab iav uas tsis yog superimposable iav)
Yuav ua li cas piv txwv ntawm conformational isomers?
Ntau cov piv txwv ntawm conformational isomerism yog cov ncauj lus kom ntxaws nyob rau lwm qhov:
- Nplhaib conformation. …
- Allylic strain - lub zog muaj feem cuam tshuam nrog kev sib hloov ntawm ib qho kev cog lus ntawm ib qho sp2 carbon thiab sp3 carbon.
- Atropisomerism - vim muaj kev txwv kev sib hloov ntawm daim ntawv cog lus.
Puas yog enantiomers configurational lossis conformational isomers?
Muaj ob hom kev teeb tsa isomers: diastereisomers thiab enantiomers. Enantiomers yog cov duab iav uas tsis yog superposable.
