Txhawm rau xam lub xeev oxidation rau carbon, siv cov lus qhia hauv qab no:

  1. Hauv daim ntawv cog lus C-H, H raug kho zoo li nws muaj oxidation xeev ntawm +1.
  2. Rau carbon bonded rau ntau electronegative tsis-hlau X, xws li nitrogen, oxygen, sulfur los yog halogens, txhua C-X daim ntawv cog lus yuav ua rau kom cov oxidation xeev ntawm carbon los ntawm 1.

Ib yam li ntawd, tus lej oxidation ntawm carbon yog dab tsi?

+4

Tsis tas li ntawd, koj yuav nrhiav tau oxidation li cas? Kev piav qhia:

  1. Tus naj npawb oxidation ntawm cov khoom dawb yog ib txwm 0.
  2. Tus lej oxidation ntawm monatomic ion sib npaug ntawm tus nqi ntawm ion.
  3. Tus naj npawb oxidation ntawm H yog +1, tab sis nws yog -1 nyob rau hauv thaum ua ke nrog tsawg electronegative ntsiab.
  4. Tus lej oxidation ntawm O hauv cov tebchaw feem ntau yog -2, tab sis nws yog -1 hauv peroxides.

Yog li ntawd, lub xeev oxidation ntawm CO yog dab tsi?

Nyob rau hauv nws cov compounds cobalt yuav luag ib txwm pom qhov +2 lossis +3 oxidation xeev Txawm hais tias lub xeev ntawm +4, +1, 0, thiab −1 paub.

Vim li cas oxidation ntawm cov organic tebchaw?

Oxidation yog thaum cov pa roj carbon atoms tau bonds rau oxygen, xws li yog hais hauv qhov piv txwv no. Nws ua tau kuj xa mus rau tej yam tshwm sim uas txav electrons. Oxidation yog Qhov tseeb qhov nce ntawm oxygen, uas ua rau kom muaj txiaj ntsig zoo ntawm lub atom.
