A stereochemical formula yog ib tug peb-dimensional sawv cev ntawm ib hom molecular, xws li, los yog raws li ib tug projection nyob rau hauv lub dav hlau siv cov pa bold los yog dotted kab los qhia cov orientation ntawm cov bonds rau pem hauv ntej thiab nram qab lub dav hlau feem.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog kev sib raug zoo stereochemical?

Chemists nyiam categorize qhov zoo sib xws ntawm ob molecules ib yam li koj xav tau rau cov kev sib raug zoo nruab nrab ntawm ob tug neeg. Qib ntawm qhov zoo sib xws ntawm ob lub molecules tuaj yeem pab kwv yees lawv qhov zoo sib xws hauv cov khoom thiab cov tshuaj reactivity. Ob lub molecules uas zoo sib xws yog hu ua isomers.

Tsis tas li ntawd, vim li cas peb thiaj xav tau stereochemistry? Siv stereochemistry , chemists tuaj yeem ua haujlwm tawm kev sib raug zoo ntawm cov molecules sib txawv uas yog tsim los ntawm tib lub atoms. Lawv tuaj yeem kawm txog cov txiaj ntsig ntawm lub cev lossis cov khoom siv lom neeg cov kev sib raug zoo no muab cov molecules. Ib feem tseem ceeb ntawm stereochemistry yog kev kawm ntawm chiral molecules.

Cov lus nug tseem yog, nws txhais li cas los qhia stereochemistry?

Stereochemistry , ib tug subdiscipline ntawm chemistry, muaj kev kawm txog cov txheeb ze spatial kev npaj ntawm atoms uas tsim cov qauv ntawm molecules thiab lawv manipulation. Stereochemistry spans tag nrho cov spectrum ntawm organic, inorganic, lom, lub cev thiab tshwj xeeb tshaj yog supramolecular chemistry.

Dab tsi yog qhov txawv ntawm enantiomers thiab diastereomers?

Muaj ob hom stereoisomers- enantiomers thiab diastereomers . Enantiomers muaj chiral cov chaw uas yog daim iav duab thiab tsis-superimposable. Cov neeg txom nyem muaj chiral cov chaw uas tsis yog superimposable tab sis tsis yog daim iav duab. Muaj peev xwm muaj ntau tshaj 2 nyob ntawm seb muaj pes tsawg tus stereocenters.
