Stereoisomerism yog qhov kev npaj ntawm atoms hauv cov molecules uas nws qhov kev sib txuas tseem zoo ib yam tab sis lawv qhov chaw nyob sib txawv hauv txhua isomer. Ob hom tseem ceeb ntawm stereoisomerism yog: DiaStereomerism (xws li 'cis-trans isomerism') Optical Isomerism (tseem hu ua 'enantiomerism' thiab 'chirality')

Yog li, dab tsi yog stereoisomers piv txwv?

Qhov yooj yim tshaj plaws piv txwv ntawm geometric isomers yog cis-2-butene thiab trans-2-butene. Nyob rau hauv txhua molecule, ob daim ntawv cog lus yog nruab nrab ntawm carbons 2 thiab 3. Rau piv txwv , oleic acid yog lub npe hu ua molecular nyob rau sab laug uas nws cov tshuaj formula C18H34O2 thiab uas muaj cis taw qhia ob daim ntawv cog lus ntawm carbons 9 thiab 10.

Ib tug kuj yuav nug, dab tsi yog enantiomer hauv organic chemistry? 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.

Yog li ntawd, dab tsi yog stereoisomers hauv chemistry?

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 nyob txawv ntawm qhov chaw. Optical isomers yog cov molecules uas yog daim iav duab ntawm ib leeg. Feem ntau cov iav duab molecules no hu ua enantiomers.

Vim li cas stereoisomers tseem ceeb?

Qhov tseem ceeb ntawm stereoisomers Nyob rau hauv ib tug lom system isomers yog cov tebchaw uas muaj tib lub qauv molecular tab sis txawv qauv qauv. Stereoisomers yog isomers uas muaj tib qhov sib lawv liag ntawm cov atoms sib txuas, tab sis lawv txawv ntawm lawv qhov kev taw qhia peb sab hauv qhov chaw.
