Bromobenzene tsis hnov qab nrog rau sodium iodide sodium iodide Sodium iodide (tshuaj formula NaI ) yog ib qho ionic compound tsim los ntawm tshuaj tiv thaiv ntawm sodium hlau thiab iodine. Raws li cov qauv txheej txheem, nws yog cov khoom dawb, dej-soluble uas muaj 1: 1 sib xyaw ntawm sodium cations (Na+) thiab iodide anions (I -) nyob rau hauv ib tug siv lead ua lattice. https://en.wikipedia.org › wiki › Sodium_iodide

hauv acetone, lossis nrog nyiaj nitrate hauv ethanol.
Vim li cas Bromobenzene qhia meej cov tshuaj tom qab ntxiv nrog SN1 thiab SN2 reagents?
Bromobenzene tsis ua haujlwm hauv SN1 thiab SN2. Cov pa roj carbon-bromine daim ntawv cog lus muaj zog heev thiab txawm tias bromine yog qhov zoo dua tawm hauv pawg nws yuav tsis tawm ntawm lub nplhaib uas muaj ntxhiab; ntxiv rau phenyl carbocations tsis ruaj khov heev.
Qhov twg alkyl halides tsis hnov mob nrog ethanolic nyiaj nitrate?
Benzyl, allyl, thiab tertiary halides teb tam sim nrog nyiaj nitrate. Thib ob thiab thawj halides tsis hnov tsw ntawm chav tsev kub tab sis hnov qab yooj yim thaum rhuab. Aryl thiab vinyl halides tsis hnov tsw li. Cov txheej txheem: Hauv txhua lub raj, ntxiv 2 mL ntawm 2% ethanolic silver nitrate tov.
Puas yog 2 Chlorobutane hnov mob nrog nyiaj nitrate?
Cov tshuaj tiv thaiv zaum kawg nrog 2-chlorobutane thiab 1% nyiaj nitrate hauv 1: 1 sib xyaw ntawm ethanol thiab dej yog cov tshuaj tiv thaiv SN1, tab sis txij li cov nag lossis daus tsim tsuas yog cua sov, cov kuab tshuaj tsis zoo, lossis polar., raws li nws tau nyob hauv thawj ntu ntawm qhov kev sim nrog thawj zaug SN1 cov tshuaj tiv thaiv.
AgNO3 ua dab tsi hauv cov tshuaj chemical?
Silver nitrate tov tuaj yeem yog siv kom paub seb qhov twg halogen muaj nyob rau hauv qhov xav tias halogenoalkane.
