Thaum benzene reacted nrog iodine cov tshuaj tiv thaiv yog thim rov qab hauv xwm. Nws ua rau kev tsim cov reactants rov qab. Yog li thiab oxidizing tus neeg sawv cev zoo li HNO3 oxidizes HI tsim nyob rau hauv cov tshuaj tiv thaiv rau I2 khaws cov tshuaj tiv thaiv rau pem hauv ntej.
Vim li cas iodination ntawm benzene thim rov qab?
Rau Iodination, cov tshuaj tiv thaiv yog endothermic nrog 12kJ / mol ntawm lub zog nqus Yog li, nws tsis tuaj yeem ua tiav siv txoj kev siv cov Lewis acid catalyst thiab yuav tsum muaj cov tshuaj oxidizing muaj zog. Qhov no yog vim, I2 ntxiv rau Benzene reversibly generating HI.
Vim li cas iodination ntawm Haloalkane siv conc HNO3?
Iodination ntawm alkanes yog ua nyob rau hauv muaj cov tshuaj oxidizing vim ib qho ntawm cov khoom yog hydrogen iodide, uas yog ib tug muaj zog txo tus neeg sawv cev thiab nws converts alkyl iodide rov qab mus rau ib tug. alkane.… Txij li thaum cov tshuaj tiv thaiv yog thim rov qab, peb siv cov tshuaj oxidizing xws li $HN{O_3}$ lossis $HI{O_3}$ los rhuav tshem HI.
Vim li cas iodination ntawm benzene nyuaj?
Yog vim li cas: (i) I2 yog qhov tsawg tshaj plaws ntawm tag nrho cov halogens vim C-I daim ntawv cog lus tsim muaj zog dua C-Cl thiab C-Br daim ntawv cog lus Iodobenzene li tsim rov qab mus rau benzene. … Iodination kuj tseem tuaj yeem ua rau muaj mercuric oxide uas tshem tawm HI li insoluble mercuric iodide.
HNO3 ua haujlwm dab tsi hauv cov tshuaj tiv thaiv benzene nrog I2 los tsim iodobenzene?
YNyob hauv kev tsim ntawm iodobenzene, HNO
3 ua ua ib qho reagent uas oxidizes iodine molecule rau iodine cation (ie I + ). Cov iodine cation ua raws li electrophile thiab dhau los ua cov tshuaj tiv thaiv electrophilic los tsim cov iodobenzene.
