Cov txheej txheem rau npe ib qho kev sib koom ua ke yog: thaum npe ib complex ion, cov ligands npe ua ntej cov hlau ion. Sau tus npe ntawm ligands nyob rau hauv cov nram qab no kev txiav txim: nruab nrab, tsis zoo, zoo. Yog tias muaj ntau lub ligands ntawm tib hom nqi, lawv yog npe nyob rau hauv alphabetical kev txiav txim.

Ib yam li ntawd, kev sib koom ua ke nrog piv txwv yog dab tsi?

Kev sib koom ua ke suav nrog cov tshuaj xws li vitamin B12, hemoglobin, thiab chlorophyll, dyes thiab pigments, thiab catalysts siv los npaj cov organic. Kev sib koom ua ke muaj lub hauv paus hlau atom puag ncig los ntawm nonmetal atoms los yog pawg ntawm atoms, hu ua ligands.

Tom qab ntawd, lo lus nug yog, qhov kev sib koom ua ke txhais li cas?:ib compound los yog ion nrog lub hauv paus feem ntau yog xim hlau atom lossis ion ua ke los ntawm koom tes bonds nrog tus naj npawb ntawm cov ions nyob ib puag ncig, pawg, lossis molecules. - hu ua kev sib koom ua ke.

Xav txog qhov no, koj ua li cas lub npe ntawm cov khoom siv hlau?

Lub npe Ionic Compounds nrog Transition Hlau

  1. Sau lub npe ntawm kev hloov pauv hlau raws li qhia nyob rau ntawm Lub Sijhawm Lub Sijhawm.
  2. Sau lub npe thiab them nyiaj rau cov tsis yog hlau.
  3. Siv tag nrho cov nqi ntawm cov hlau tsis yog hlau (los yog polyatomic ion) nrhiav tus nqi ntawm cov hlau hloov.

Dab tsi yog hom ligands?

Hom ntawm Ligands

  • Unidentate ligands: Ligands nrog tsuas yog ib qho pub dawb atom, piv txwv li. NH3, Cl-, F- lwm.
  • Bidentate ligands: Ligands nrog ob lub atoms pub dawb, piv txwv li. ethylenediamine, C2O42-(oxalate ion) thiab lwm yam.
  • Tridentate ligands: Ligands uas muaj peb lub atoms pub dawb rau ib ligand, xws li. (dien) Diethyl triamine.
