F−<Cl−<NO2−<CN−<C2O42−

Yuav ua li cas yog ligands?

Ligands tuaj yeem npaj rau hauv lub npe hu ua spectrochemical series nyob rau hauv kev txiav txim los ntawm muaj zog π txais (correlated nrog qis spin, muaj zog teb, thiab loj δ qhov tseem ceeb) kom muaj zog π pub (txuas nrog siab spin, tsis muaj zog teb, thiab me δ values) raws li nram no: CO, CN⁻ > 1, 10-phenanthroline > NO^{2 −} > en > NH₃ > NCS⁻ > H₂O > F ⁻ > RCOO^-

Qhov twg hauv qab no yog qhov tseeb hauv spectrochemical series?

Cov series uas txheeb qhov loj ntawm ${{Delta }_{{mathrm O}}}$ ntawm ligand yog lub npe hu ua spectrochemical series. Los ntawm stereochemical series, peb tuaj yeem pom tias qhov tseeb ascending kev txiav txim ntawm ligand teb lub zog ntawm lub ligand muab yog kev xaiv (C) [{{I}^{-}} < {{F}^{- }} < {{H}_{2}}O < C{{N}^{-}} < CO]

Dab tsi yog spectrochemical series muab qhov kev txiav txim?

Spectro-chemical series yog ib series uas cov ligands tau teem nyob rau hauv kev txiav txim ntawm kev loj hlob ntawm splitting lawv tsim Qhov kev txiav txim yog. I– < Br^– < SCN^– < Cl^– < S^{2 –} < F ^– < OH^– < C_{2 O}42 < H₂ O < NCS^–< edta^4– < NH₃ < en < CN^{– < CO.}

Dab tsi yog spectrochemical series txoj cai koob?

A spectrochemical series yog daim ntawv teev cov ligands xaj ntawm ligand lub zog thiab cov npe ntawm cov hlau ions raws li tus lej oxidation, pab pawg thiab nws tus kheej.
