thawj kauj ruam hauv nitration ntawm benzene yog ua kom HNO 3nrog sulfuric acid los tsim cov electrophile muaj zog, cov nitronium ion. Vim tias nitronium ion yog ib qho zoo electrophile, nws raug tawm tsam los ntawm benzene los tsim Nitrobenzene.
Dab tsi yog electrophile hauv Sulphonation ntawm benzene?
Yog li, lub zog electrophile hauv sulfonation ntawm benzene yog sulphur trioxide.
Yuav ua li cas yog cov electrophile hauv Sulphonation cov tshuaj tiv thaiv nws tsim li cas?
-Thaum sulphonation ntawm benzene, benzene yog rhuab nrog ib tug sib tov ntawm sulfur trioxide thiab sulfuric acid. Hauv cov tshuaj tiv thaiv, benzene sulfonic acidyog tsim. … Yog li, oxygen hauv sulfuric acid rub ib qho hluav taws xob mus rau nws tus kheej thiab tsim ib qho electrophile SO3 S O 3.
Yuav ua li cas cov electrophile tsim nyob rau hauv nitration ntawm benzene?
Sulphuric acid yog cov kua qaub uas muaj zog thiab yog li nws pub ib qho proton rau nitric acid uas ua rau tsim cov dej nrog rau nitronium ion uas yog lub zog electrophile. … Li no, tiam ntawm electrophile nyob rau hauv nitration ntawm benzene tshwm sim los ntawm protonation ntawm nitric acid nrog kev pab ntawm sulfuric acid.
Electrophile hauv cov tshuaj tiv thaiv electrophilic hloov pauv ntawm benzene siv SO3 thiab h2so4 yog dab tsi?
Fuming sulfuric acid, H2S2O7, tuaj yeem xav txog raws li kev daws teeb meem ntawm SO3 hauv sulfuric acid - thiab yog li yog ib qhontau nplua nuj los ntawm SO3. Sulphur trioxide yog ib qho khoom siv hluav taws xob vim nws yog ib qho polar molecule uas muaj tus nqi zoo ntawm cov sulfur atom.
