Teb tiav: Ib qho meso compound lossis meso isomer yog tus tswv cuab uas tsis muaj qhov muag pom ntawm ib pab pawg neeg stereoisomers, uas muaj tsawg kawg yog ob lub qhov muag pom. Qhov no txhais tau hais tias cov molecule tsis yog chiral txawm hais tias nws muaj ob los yog ntau tshaj stereo genic centres. … Cyclic compounds kuj yog theoretically meso.
Cov tshuaj meso puas muaj cov haujlwm kho qhov muag?
Ib qho meso compound lossis meso isomer yog tsis yog tus tswv cuab ntawm qhov muag pom ntawm ib pawg ntawm cov stereoisomers, tsawg kawg yog ob qho uas yog optically active. Qhov no txhais tau hais tias txawm tias muaj ob lossis ntau lub chaw stereogenic, cov molecule tsis yog chiral.
Vim li cas cov tshuaj meso tsis qhia txog kev ua haujlwm kho qhov muag?
Meso tebchaw yog cov tebchaw uas nws cov molecules yog superimposable ntawm lawv daim iav duab txawm tias muaj cov pa roj carbon atom asymmetric. … Ob ob halves ntawm lub molecule tig lub dav hlau ntawm polarized lub teeb nyob rau hauv opposite direction thiab li no tshem tawm cov nyhuv ntawm ib leeg thiab ua rau lub molecule optically inactive.
Qhov twg tuaj yeem muaj nyob ua qhov kho qhov muag isomers?
Compound F, C4H10O, muaj nyob ua ib khub ntawm optical isomers.
Puas optically inactive compounds qhia optical isomerism?
Nyob rau hauv thawj lo lus nug muaj dav hlau ntawm symmetry thiab tsis muaj chiral chaw yog li ntawd molecule yog symmetric li no tsis qhia optical isomerism. Hauv 2, tsis muaj tag nrho 4, optically tsis ua haujlwm. Nyob rau hauv 3 muaj dav hlau ntawm symmetry li ob leeg Cl yog tib sab.
