Nyob rau hauv oxime, nitrogen txuas rau carbon los ntawm ob daim ntawv cog lus (II), thaum nyob rau hauv nitroso daim ntawv, nitrogen yog txuas rau oxygen los ntawm ob daim ntawv cog lus (I). Ntau dua qhov sib txawv ntawm electronegativity ntawm atoms, muaj zog dua yog daim ntawv cog lus. Yog li daim ntawv nitroso ruaj khov dua li daim ntawv oximino.
Tus neeg tautom qab twg ruaj khov dua?
Ua tiav cov lus teb ib kauj ruam:
alpha-hydrogen hauv nws. Qhov no alpha-hydrogen yog hloov los yog tsiv mus rau nitrogen. vim tias tom kawg muaj cov pa roj carbon- nitrogen ob daim ntawv cog lus uas ruaj khov heev. Yog li, imine yog ruaj khov dua li daim ntawv enamine.
Qhov twg Tautomer isomer ruaj khov dua?
Nyob rau hauv peb tautomer peb tau conjugated ob daim ntawv cog lus uas muab ntxiv stability yog li IIIyog qhov ruaj khov tshaj plaws. Ntawm thawj thiab thib ob tautomers, thawj tautomer yog daim ntawv enol thiab qhov thib ob yog daim ntawv keto. Peb paub tias keto ruaj khov dua li enol tautomer yog li qauv II ruaj khov dua li qauv I.
Vim li cas Tautomerism ruaj khov?
Hydrogen Bonding . Cov neeg txais nyiaj hydrogen nyob ze ua kom ruaj khov rau daim ntawv enol. Thaum ib pab pawg Lewis yooj yim nyob ze, daim ntawv enol tau ruaj khov los ntawm kev sib txuas nrog hydrogen.
Tautomerism chemistry yog dab tsi?
tautomerism, qhov muaj nyob ntawm ob lossis ntau dua cov tshuaj lom neeg uas muaj peev xwm ua tau yooj yim sib cuam tshuam, ntau zaus tsuas yog pauv cov hydrogen atom ntawm obLwm cov atoms, rau ob qho uas nws tsim ib daim ntawv cog lus.
