Illustrated Glossary of Organic Chemistry - Nplhaib tig ( rooj zaum tig ) Nplhaib tig ( rooj zaum tig ): Kev hloov ntawm ib cyclohexane lub rooj zaum conformation rau lwm, los ntawm kev sib hloov nyob ib ncig ntawm ib daim ntawv cog lus. Cyclhexane nplhaib tig ua rau axial hloov pauv los ua equatorial, thiab equatorial substituents ua axial.

Ib yam li ntawd, lub rooj zaum flips conformational isomers?

Los ntawm Cyclhexane " Lub rooj zaum Flip "Kev sib txuas tib yam, sib txawv cov duab - qhov no yog lub ntsiab lus ntawm " conformational isomers "yog tias muaj ib qho.

Tsis tas li ntawd, dab tsi yog flipping hauv chemistry? Hauv cov organic chemistry , ib lub nplhaib tig (tseem hu ua lub nplhaib inversion lossis lub nplhaib thim rov qab) yog kev sib hloov ntawm kev sib hloov ntawm lub nplhaib sib npaug (piv txwv li, los ntawm lub rooj zaum conformer mus rau lwm lub rooj zaum conformer) uas ua rau muaj kev sib pauv ntawm cov haujlwm tsis sib xws.

Yog li ntawd, yog lub rooj zaum tig yog enantiomer?

(Daim iav duab kev sib raug zoo tuaj yeem pom los ntawm kev sib piv "ntiv nplhaib tig "conformation ntawm Lub rooj zaum Projection ntawm txoj cai rau tam sim no conformation ntawm lub Lub rooj zaum Projection ntawm sab laug. Rau kev qhia txog yuav ua li cas ua ib lub nplhaib " tig , " nyem qhov no.) Yog li ntawd, cov molecules yog cov enantiomers.

Vim li cas ib nrab lub rooj zaum tsis ruaj khov?

Cov ib nrab lub rooj zaum daim ntawv yog qhov tsawg kawg nkaus ruaj khov vim qhov siab tshaj plaws. Vim muaj kev cuam tshuam ntawm ob lub flagpole hydrogens, muaj steric strain nyob rau hauv lub nkoj daim ntawv thiab kuj torsional strain yog tam sim no. Nws yog 6.5 kcal / mol tsawg ruaj khov dua li lub rooj zaum daim ntawv.
