SN2 cov tshuaj tiv thaiv yog nyiam los ntawm qhov tsawg tshaj plaws sterric hindrance yog qhov feem ntau reactive tom qab conjugated alkyl halide ua qhov twg tus nqi yog nrawm los ntawm kev sib txuas hauv lub xeev kev hloov pauv.
Tsis tas li ntawd, qhov twg yog qhov ntau dua ntawm cov tshuaj tiv thaiv sn2?
Nyob rau hauv C6H5Cl, Cl- ion yog txuas ncaj qha mus rau ib pawg uas muaj ntxhiab tsw uas ua rau ntau steric hinderance, yog li ua kom tsawg reactive rau SN2 cov tshuaj tiv thaiv . Ntawm qhov tod tes, C6H5CH2Cl yog 1. Vim muaj kev cuam tshuam tsawg dua, nws yog ntau reactive rau SN2 cov tshuaj tiv thaiv.
Tom qab ntawd, lo lus nug yog, yog 2 Bromopentane optically nquag siv? Kev piav qhia: 2 - broopentane cov tshuaj yog ib optical nquag compound vim nws muaj asymmetric carbon (chiral carbon).
Tom qab ntawd, lo lus nug yog, qhov twg molecule yog qhov reactive tshaj plaws hauv sn2 cov tshuaj tiv thaiv?
Ib tug ntawm feem ntau reactive molecules koom nrog kev hloov pauv cov tshuaj tiv thaiv yog alkyl halides. Txawm li cas los xij, muaj ntau qhov kev txiav txim siab uas yuav tsum nco ntsoov txhawm rau txiav txim siab yog tias tus SN 2 mechanism piav txog koj tshuaj tiv thaiv . Ua ntej, cia peb saib qhov yooj yim SN2 cov tshuaj tiv thaiv ; methyl chloride thiab NaOH tsim methanol thiab NaCl.
Dab tsi yog sn2 cov tshuaj tiv thaiv hauv organic chemistry?
SN 2 Txhais. Cov SN2 cov tshuaj tiv thaiv - Kev Hloov Nucleophilic nyob rau hauv uas tus nqi txiav txim siab kauj ruam muaj 2 yam. - SN2 cov tshuaj tiv thaiv yog bimolecular nrog ib txhij-ua daim ntawv cog lus thiab nyiaj-tawg cov kauj ruam.
