Yog vim li cas Iodination ntawm Benzene nyuaj ? Txhawm rau kom txaus siab rau qhov xwm txheej no, electron pub dawb pab pawg txuas nrog lub nplhaib phenyl ua rau nws ntau dua nucleophilic nyiam dua tsis hloov pauv. Benzene . Tsis tas li ntawd, qhov electrophilicity ntawm halogen yog nce los ntawm kev siv Lewis acid catalyst li no ua rau nws ntau reactive.

Ua kom pom qhov no, vim li cas ionization ntawm benzene nyuaj?

vim iodination benzene nyuaj . Iodoarenes kuj yog nyuaj rau synthesis vim hais tias cov tshuaj tiv thaiv yog reversible thiab HI tsim yog ib tug muaj zog txo tus neeg sawv cev los txo iodobenzene rov qab mus rau tshuaj benzene.

Tom qab, lo lus nug yog, yog vim li cas hno3 ntxiv rau iodination ntawm benzene? hno3 ntxiv thaum lub sij hawm iodination ntawm benzene . Iodination ntawm benzene yog ua nyob rau hauv lub xub ntiag ntawm acidic oxidising tus neeg saib xyuas xws li nitric acid. HNO3 yog ib tug muaj zog oxidising tus neeg sawv cev thiab li no nws yuav pab tau tshem ntawm electron ntawm I2 convert sa I+. HNO yuav tau noj hauv cov tshuaj tiv thaiv.

Ib yam li ntawd, koj tuaj yeem nug, yog vim li cas iodination ncaj qha ntawm benzene tsis tuaj yeem ua tau?

Direct iodination ntawm benzene tsis tuaj yeem ua tau vim hais tias cov tshuaj tiv thaiv yog thim rov qab thiab HI thiaj li tsim nyob rau hauv cov tshuaj tiv thaiv yog ib tug muaj zog txo tus neeg sawv cev uas txo iodobenzene rov qab mus rau tshuaj benzene.

Vim li cas iodination ncaj qha tsis ua tau?

Iodoarenes kuj nyuaj rau kev sib txuas vim tias cov tshuaj tiv thaiv rov qab tau thiab cov HI uas tsim tawm yog tus neeg sawv cev muaj zog los txo cov iodobenzene rov qab rau benzene.
