Piv txwv li, a sab xis thiab sab laug-tes hnab looj tesyog daim iav duab ntawm ib leeg uas tsis tuaj yeem superimposed. Ib yam yog qhov tseeb rau ob daim iav duab tsev peb tau tham txog ua ntej. Tsis muaj txoj hauv kev los tig lawv ib ncig kom lawv yog tib yam khoom - lawv yuav ib txwm txawv ntawm qhov chaw peb sab.
Stereoisomerism muab piv txwv yog dab tsi?
Stereoisomers yog molecules uas muaj tib lub qauv molecular thiab sib txawv tsuas yog nyob rau hauv lawv cov atoms yog teem rau hauv peb-dimensional qhov chaw thiab cov stereoisomer qeb muaj ob peb lwm subcategories. Ob hom stereoisomers tseem ceeb yog geometrical isomers thiab optical isomers.
3 hom stereoisomers yog dab tsi?
Puas yog lawv txoj cai isomers (tib qauv qauv, sib txuas sib txawv), stereoisomers (kev sib txuas tib yam, kev sib txawv), enantiomers (stereoisomers uas tsis yog-superimposable iav duab) lossis diastereomers (stereoisomers uas tsis yog daim iav uas tsis yog superimposable.
Koj pom cov piv txwv stereoisomers li cas?
Tus qauv rau kev nrhiav tus lej siab tshaj plaws ntawm stereoisomers X yog X=2 , qhov twg n yog tus naj npawb ntawm stereogenic atoms hauv cov molecule. Tus formula X=2 ntseeg tau muab qhov siab tshaj plaws ntawm cov stereoisomers, tab sis nyob rau hauv cov xwm txheej ntawm symmetry siab nws tsis muab tus lej tiag.
Dab tsi yog hu ua stereoisomers?
Ob lub molecules yogpiav raws li stereoisomers yog lawv yog ua los ntawm tib lub atoms txuas nrog tib yam, tab sis cov atoms nyob txawv qhov chaw. Qhov txawv ntawm stereoisomers tsuas yog pom tau thaum qhov kev npaj peb-dimensional ntawm cov molecules raug txiav txim siab.
