A stereochemical formula yog a peb-dimensional sawv cev ntawm ib hom molecular, xws li, lossis raws li kev kwv yees rau lub dav hlau siv cov kab bold lossis dotted los qhia cov orientation ntawm daim ntawv cog lus rau pem hauv ntej thiab nram qab ntawm lub dav hlau feem. … Saib ntxiv: qauv qauv, qauv qauv.
txhais li cas los ntawm stereochemical hauv chemistry?
1: ib ceg ntawm chemistry uas cuam tshuam nrog kev sib hloov ntawm cov atoms thiab pawg hauv cov molecules. 2: Kev sib txuas ntawm cov atoms thiab pawg hauv ib qho kev sib txuas thiab nws qhov kev sib raug zoo ntawm cov khoom sib txuas.
Koj piav qhia txog kev siv tshuaj zoo li cas?
Stereochemistry yog txoj kev kawm ntawm peb-dimensional qauv ntawm moleculesCov cis thiab trans isomers yog cov qauv ntawm stereoisomers, sib txawv ntawm cov qauv tsuas yog nyob rau hauv qhov chaw ntawm lub atoms ntawm lub molecule nyob rau hauv peb-dimensional qhov chaw. Xws li stereoisomers tuaj yeem muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg.
Yuav ua li cas yog cov tshuaj formula?
Ib qho khoom sib xyaw yog ib yam khoom tsim los ntawm kev faib ua feem ntawm ob lossis ntau lub ntsiab lus. Cov tshuaj formula qhia peb cov naj npawb ntawm atoms ntawm txhua lub ntsiab lus hauv ib qho chawNws muaj cov cim ntawm cov atoms ntawm cov ntsiab lus tam sim no nyob rau hauv lub compound nrog rau pes tsawg tus muaj rau txhua lub caij hauv daim ntawv subscripts.
Vim li cas thiaj hu ua stereochemistry?
Lo lus "stereochemistry" yog muab los ntawm Greek "stereos" lub ntsiab lus ruaj khov- nws yog hais txog chemistry nyob rau hauv peb qhov ntev Vim tias yuav luag tag nrho cov organic molecules yog peb seem (nrog rau qhov kev zam. ntawm qee qhov olefins thiab aromatics yuav tsum tau tham tom qab), stereochemistry tsis tuaj yeem suav tias yog ib ceg ntawm chemistry.
