Hauv cis isomer cov methyl pawg nyob rau tib sab; thaum lawv nyob rau sab nraud ntawm trans isomer. Isomers uas txawv tsuas yog nyob rau hauv lub spatial orientation ntawm lawv cov atoms yog hu ua stereoisomers.

Kuj paub, koj tuaj yeem paub qhov txawv ntawm stereoisomers li cas?

Ob lub molecules tau piav raws li stereoisomers Yog tias lawv tau ua los ntawm tib lub atoms txuas nrog tib lub sijhawm, tab sis cov atoms yog qhov sib txawv hauv qhov chaw. Cov Qhov sib txawv ntawm stereoisomers tuaj yeem pom tsuas yog thaum peb-seem txheej txheem ntawm cov molecules txiav txim siab.

Kuj Paub, koj yuav paub li cas yog tias ib yam dab tsi yog enantiomer? Cov kab hauv qab rau hnub no: koj tuaj yeem ua tau qhia yog tias cov tshuaj molecules cov enantiomers los yog diastereomers los ntawm saib lawv (R, S) cov qauv. Enantiomers yog cov tsis-superimposable mirrorimages ntawm ib leeg. Thov zam txim rau kuv thaum kuv thawb lub Caps Lock khawm: ENANTIOMERS YUAV UA LI CAS YUAV UA LI CAS R, SIJ HAWM.

Tsuas yog li ntawd, koj tuaj yeem paub qhov txawv ntawm stereoisomers thiab kev cai lij choj isomers?

Constitutional isomers feem ntau muaj kev sib txuas sib txawv thiab stereoisomers muaj cov kev sib txuas zoo ib yam tab sis txawv hauv kev npaj spatial. enantiomers yog stereoisomers uas yog tsis-superimposeable daim iav duab ntawm ib leeg.

Cov piv txwv stereoisomers yog dab tsi?

Ib tug paub ntau piv txwv ntawm geometricisomers hauv biochemistry yog cis thiab trans fats. Qhov thib ob majorclass ntawm stereoisomers yog cov molecules uas muaj qhov chaw anasymmetric uas tsis yog superimposable ntawm ib leeg.
