(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.

Yog 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.

Qhov thib ob, puas yog enantiomers tib lub ntsiab lus? Enantiomers yog khub ntawm tshuaj sib xyaw nrog raws nraim cov ib yam kev sib txuas tab sis opposite duab peb-dimensional. Enantiomers tsis yog cov ib yam ib leeg; ib enantiomer tsis tuaj yeem superimposed rau lwm tus. Enantiomers yog daim iav duab ntawm ib leeg.

Ib yam li ntawd, lub rooj zaum flip yog dab tsi?

Illustrated Glossary of Organic Chemistry - Ntiv 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.

Dab tsi ua rau lub rooj zaum conformation ruaj khov?

Yog vim li cas yog tias thaum hloov pauv nyob rau hauv txoj hauj lwm axial, muaj feem yuav ntau kev cuam tshuam tsis zoo nrog lwm cov axial atoms ntawm tib sab. Thaum cov neeg hloov pauv nyob hauv txoj haujlwm equatorial, lawv nyob deb ntawm ib leeg. Qhov no nce lub ruaj khov ntawm kev sib haum xeeb.
