Tsuas yog ua kom pom tseeb, meso compound yog cov molecule uas muaj chiral chaw tab sis kuj muaj lub dav hlau sab hauv ntawm symmetry. Qhov no ua rau cov molecule achiral: nws tsis muaj enantiomer, thiab nws tsis tig dav hlau polarized teeb.
Puas yog meso compounds puas muaj kev puas tsuaj?
Meso compounds yog achiral (optically inactive) diastereomers ntawm chiral stereoisomers.
Puas yog meso compound yuav tsum muaj Stereocenter?
Meso tebchaw tuaj yeem muaj nyob hauv ntau hom ntawv xws li pentane, butane, heptane, thiab txawm tias cyclobutane. Lawv tsis tas yuav tsum yog ob lub stereocenters, tab sis tuaj yeem muaj ntau dua.
Cov tshuaj meso puas muaj stereochemistry?
Yog A yog meso compound, nws yuav tsum muaj ob los yog ntau tshaj stereocenters, ib lub dav hlau sab hauv, thiab lub stereochemistry yuav tsum R thiab S. Nrhiav ib lub dav hlau sab hauv, los yog internal mirror, uas nyob nruab nrab ntawm lub compound. stereochemistry (xws li R lossis S) yog qhov tseem ceeb heev hauv kev txiav txim siab seb nws puas yog meso compound lossis tsis.
Koj paub qhov txawv ntawm meso tebchaw thiab enantiomers li cas?
Meso tebchaw thiab enantiomers yog cov organic tebchaw uas muaj stereocenters. Lawv txawv ntawm ib leeg hauv ntau yam. Qhov sib txawv tseem ceeb ntawm meso compound thiab enantiomers yog qhov meso tebchaw muaj daim iav zoo tib yam thaum enantiomers muaj daim iav uas tsis yog superimposable.
