Nyob rau hauv chemistry, conformational isomerism yog ib daim ntawv ntawm stereoisomerism uas cov isomers tuaj yeem hloov pauv tau los ntawm kev sib hloov ntawm kev sib hloov ntawm kev ua haujlwmib daim ntawv cog lus (saib rau daim duab ntawm ib daim ntawv cog lus sib hloov). … Kev sib hloov ntawm ib daim ntawv cog lus koom nrog kev kov yeej lub zog sib hloov los cuam tshuam ib qho kev sib hloov mus rau lwm qhov.
Yuav ua li cas yog conformational isomers?
Conformational Isomers (Conformers): Ob lub molecules nrog tib lub teeb tab sis txawv conformation. Conformational isomers yog ib ntus sib txawv ntawm tib lub molecule thiab vim li no tsis raug cais raws li isomers hauv qee phau ntawv.
Puas muaj pes tsawg tus isomers muaj?
Muaj ob hom ntawm conformational isomers: -Eclipsed conformational isomers: Nyob rau hauv cov isomers, cov carbons yog aligned kom cov hydrogens lined nrog ib leeg. -Staggered conformational isomers: Hauv cov isomers no, atoms sib npaug sib npaug ntawm ib leeg.
Qhov twg hauv qab no yog conformational isomers?
Tsuas xaiv C uas yog ethane qhia txog kev hloov pauv isomerism. Yog li, kev xaiv C yog qhov tseeb, raws li nws yog alkane. Nco tseg: Muaj ob daim ntawv uas conformers muaj, uas yog, staggered daim ntawv thiab eclipsed daim ntawv.
Cov piv txwv ntawm isomers yog dab tsi?
Piv txwv li, butane muaj peb tus neeg sib tw hais txog nws ob lub methyl (CH3) pawg: ob pawg neeg sib tw, uasmuaj cov methyls ± 60 ° sib nrug thiab yog enantiomeric, thiab ib qho kev tiv thaiv conformer, qhov chaw plaub cov pa roj carbon monoxide yog coplanar thiab cov khoom hloov pauv yog 180 ° sib nrug (saib rau daim duab pub dawb ntawm butane).

Dab tsi alkane yog isomer ntawm butane hu ua 2-methylpropane?
Isobutane, tseem hu ua i-butane, 2-methylpropane lossis methylpropane, yog cov tshuaj sib xyaw nrog molecular mis HC (CH3) 3. Nws yog ib qho isomer ntawm butane. Isobutane yog cov roj tsis muaj xim, tsis muaj ntxhiab tsw. Nws yog qhov yooj yim tshaj plaws alkane nrog tertiary carbon atom.
