Ib qho meso compound lossis meso isomer yog cov tswvcuab uas tsis yog kho qhov muag ntawm cov txheej txheem 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. Meso compound yog "superposable" ntawm nws daim iav duab.
Meso compound nrog piv txwv yog dab tsi?
Piv txwv 1 thiab 2 raug cais ua cov tshuaj meso vim tias lawv muaj tsawg kawg yog ob lub chaw chiral thiab sab hauv iav dav hlau, raws li qhia los ntawm cov kab tawg. Hauv Piv txwv 3, hydrogen (H) thiab chlorine (Cl) yog nyob rau sab hauv daim iav dav hlau, yog li Piv txwv 3 tseem muab faib ua meso compound.
Meso compound txhais li cas?
Meso Compounds. Meso compound yog ib achiral compound uas muaj chiral chaw. Nws yog superimposed ntawm nws daim iav duab thiab yog optically inactive txawm hais tias nws muaj ob los yog ntau tshaj stereocenters.
Puas yog meso compound a diastereomer?
Meso compounds yog achiral (optically inactive) diastereomers ntawm chiral stereoisomers.
Dab tsi yog qhov txawv ntawm meso thiab diastereomers?
Enantiomers txhua lub chaw chiral hloov … Cov neeg mob hnyav tsawg kawg yog ib lub chaw chiral hloov kev teeb tsa. Piv txwv li, yog molecule A muaj chiral chaw (R, S) nyob rau hauv molecule B yuav muaj ib tug configuration ntawm (S, S). Meso compounds yog cov tebchaw uas muaj daim iav superimposable.
