Muaj ob hom txheej txheem rau alkyl halides - SN1 thiab SN2. … Thawj thiab theem nrab alkyl halides tuaj yeem nkag musSN2 mechanism, tab sis tertiary alkyl halides hnov mob tsuas yog qeeb heev. SN1 mechanism yog ob-theem mechanism uas thawj theem yog tus nqi txiav txim kauj ruam.
Vim li cas thawj alkyl halides tsis raug SN1?
A 1° alkyl halide tsuas muaj ib pawg alkyl xwb, yog li nws kuj tsis ruaj khov Nws tsis zoo li tsim 1° carbocation hauv SN1 cov tshuaj tiv thaiv. Hloov chaw, nws yuav siv txoj hauv kev qis-zog SN2, uas cov nucleophile "kicks" cov halide tawm hauv pawg, thiab ua rau tsis muaj kev tsim cov carbocation tsis ruaj khov.
Qhov twg alkyl halide yuav raug SN1?
Vim C-I daim ntawv cog lus yog qhov tsis muaj zog ntawm tag nrho cov C-X daim ntawv cog lus, yog li, rerf-butyl iodide dhau SN1 cov tshuaj tiv thaiv yooj yim tshaj plaws.
Pob thawj alkyl halides dhau E1?
Ntawm SN1 / E1 sab, allyl halide hauv qab no, thaum thawj, tuaj yeem nkag musSN1 / E1 cov tshuaj tiv thaiv vim tias qhov tshwm sim carbocation yog ruaj khov los ntawm resonance.
Puas SN1 nyiam thawj lossis qib thib ob?
Qhov teeb meem loj rau SN1 yog kev ruaj ntseg carbocation, uas yog vim li cas nws thiaj nyiam rau tertiary > secondary >> thawj alkyl halides thiab polar aprotic protic solvents.
