Qhov sib txawv tseem ceeb ntawm intramolecular redox thiab cov tshuaj tiv thaiv redox tsis sib haum yog qhov intramolecular redox cov tshuaj tiv thaiv tshwm sim thaum ib qho molecule dhau oxidation thiab txo qis hauv tib cov tshuaj lom neeg lossis cov tshuaj sib txawv ntawm qhov sib txawv ntawm cov tshuaj tiv thaiv redox cuam tshuam nrog oxidation thiab txo qhov qub. chemical element nyob rau hauv ib lub substrate.
Intramolecular redox cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv redox tsis sib xws yog ob hom tshuaj lom neeg tsis muaj tshuaj lom neeg uas muaj oxidation thiab txo cov tshuaj tiv thaiv tshwm sim rau ib leeg. Ob qho tshuaj tiv thaiv no cuam tshuam nrog oxidation thiab txo ib nrab-kev tshwm sim tshwm sim hauv tib cov tshuaj lom neeg sib xyaw / hauv tib lub substrate molecule. Ob hom sib txawv ntawm ib leeg raws li cov khoom siv tshuaj lom neeg uas cov tshuaj tiv thaiv ib nrab tshwm sim.
Dab tsi yog Intramolecular Redox Reactions?
Intramolecular redox cov tshuaj tiv thaiv yog tshuaj lom neeg cov tshuaj tiv thaiv uas koom nrog tib lub substrate uas oxidation thiab txo qis tshwm sim hauv tib cov tshuaj lom neeg lossis hauv ob yam tshuaj sib txawv. Hauv lwm lo lus, hauv qee qhov kev cuam tshuam intramolecular redox, oxidation thiab txo qis tshwm sim hauv tib yam tshuaj lom neeg thaum nyob rau hauv lwm cov tshuaj intramolecular redox cov tshuaj tiv thaiv oxidation thiab txo qis tshwm sim hauv ob yam tshuaj sib txawv uas nyob hauv tib lub cev. Yog tias oxidation thiab txo qis tshwm sim hauv tib yam tshuaj lom neeg, ces peb hu nws ua qhov tsis sib xws.

Dab tsi yog qhov cuam tshuam Redox Reactions?
Disproportionate redox cov tshuaj tiv thaiv yog tshuaj lom neeg cov tshuaj tiv thaiv uas oxidation thiab txo qis tshwm sim hauv tib cov tshuaj lom neeg ntawm tib lub substrate molecule. Hauv cov tshuaj tiv thaiv no, ib qho substrate molecule ua haujlwm ob txoj hauv kev, oxidizing thiab txo qis ib nrab-reactions. Ntawm no, ib feem ntawm cov molecule undergoes oxidation thaum lwm qhov ntawm cov molecule undergoes txo; Txawm li cas los xij, ob qho tib si cov khoom molecular no suav nrog tib cov tshuaj lom neeg uas muaj oxidation lossis txo qis. Ib qho piv txwv yog raws li nram no:

Lwm qhov piv txwv ntawm hom tshuaj tiv thaiv no yog qhov tsis sib xws ntawm cov pa atom hauv hydrogen peroxide, H2O2 molecule. Ntawm no, cov pa oxygen hauv hydrogen peroxide molecule raug oxidation los tsim cov pa roj carbon monoxide, thiab tib lub molecule txo qis los tsim cov dej molecule.
Dab tsi yog qhov txawv ntawm Intramolecular Redox thiab Disproportionate Redox Reaction?
Redox cov tshuaj tiv thaiv yog cov tshuaj tiv thaiv uas muaj oxidation ib nrab-rooj thiab txo qis ib nrab-rooj tshwm sim rau ib leeg. Qhov sib txawv tseem ceeb ntawm intramolecular redox thiab disproportionate redox cov tshuaj tiv thaiv yog tias cov tshuaj tiv thaiv intramolecular redox tshwm sim thaum cov molecules ntawm ob yam tshuaj sib txawv nrog rau ib leeg, qhov tsis sib xws ntawm cov tshuaj tiv thaiv redox cuam tshuam nrog oxidation thiab txo ntawm ib qho molecule.
Disproportionation of C6H2(NO2)3 CH3 los ua N2 ntawm kev txo qis thiab C ntawm oxidation yog ib qho piv txwv ntawm cov tshuaj tiv thaiv intramolecular redox thaum disproportionation ntawm cov pa. atom nyob rau hauv ib tug hydrogen peroxide molecule yog ib qho piv txwv ntawm ib tug disproportionate redox cov tshuaj tiv thaiv.
Cov hauv qab no infographic qhia txog qhov sib txawv ntawm intramolecular redox thiab cov tshuaj tiv thaiv redox tsis sib xws hauv daim ntawv teev npe rau kev sib piv ntawm ib sab.
Summary – Intramolecular Redox vs Disproportionate Redox Reaction
Redox cov tshuaj tiv thaiv yog cov tshuaj tiv thaiv uas muaj oxidation thiab txo cov tshuaj tiv thaiv uas tshwm sim rau ib leeg. Qhov sib txawv tseem ceeb ntawm intramolecular redox thiab disproportionate redox cov tshuaj tiv thaiv yog tias cov tshuaj tiv thaiv intramolecular redox tshwm sim thaum cov molecules ntawm ob yam tshuaj sib txawv nrog rau ib leeg, qhov tsis sib xws ntawm cov tshuaj tiv thaiv redox cuam tshuam nrog oxidation thiab txo ntawm ib qho molecule.
