Chifukwa chiyani? Iodination za Benzene Wovuta? Kuti mukwaniritse izi, magulu opereka ma elekitironi omwe amalumikizidwa ndi mphete ya phenyl kuti ikhale ya nucleophilic ndi yabwino kuposa yosalowa m'malo. Benzene. Komanso, electrophilicity ya halogen imachulukitsidwa pogwiritsa ntchito Lewis acid catalyst potero imapangitsa kuti ikhale yogwira ntchito.

Poganizira izi, chifukwa chiyani ionization ya benzene imakhala yovuta?

chifukwa iodination wa benzene zovuta. Iodoarenes nawonso zovuta kuphatikizika chifukwa zomwe zimachitikazo zimasinthika ndipo HI yopangidwa ndi mphamvu yochepetsera kuchepetsa iodobenzene kubwerera ku benzene.

Pambuyo pake, funso ndilakuti, chifukwa chiyani Hno3 amawonjezeredwa ku ayodini wa benzene? hno3 anawonjezera pa ayodini wa benzene. Iodine wa benzene zimachitika pamaso pa acidic oxidizing wothandizira monga nitric acid. HNO3 ndi amphamvu okosijeni wothandizira choncho zimathandiza kuchotsa elekitironi ku I2 kusintha kukhala I+. HNO idzadyedwa momwemo.

Mofananamo, mungafunse, chifukwa chiyani ayodini mwachindunji wa benzene sizingatheke?

Kuyika ayodini mwachindunji wa benzene sikutheka chifukwa momwe zimakhalira zimasinthika ndipo HI yomwe imapangidwa munjirayo imakhala yochepetsera kwambiri yomwe imachepetsa iodobenzene kubwerera ku benzene.

Chifukwa chiyani ayodini mwachindunji sizingatheke?

Ma Iodoarenes nawonso ndi ovuta kupanga chifukwa momwe zimachitikira zimatha kusintha ndipo HI yopangidwa ndi mphamvu yochepetsera kuchepetsa iodobenzene kubwerera ku benzene.
