Bidentate ligands yog Lewis hauv paus uas pub ob khub ("bi") ntawm cov hluav taws xob rau cov hlau atom. Bidentate ligands feem ntau hu ua chelating ligands ("chelate" yog muab los ntawm Greek lo lus "claw") vim tias lawv tuaj yeem "lob" cov hlau atom hauv ob qhov chaw.
Tus piv txwv bidentate ligand yog dab tsi?
Bidentate ligands muaj ob lub atoms pub dawb uas tso cai rau lawv los khi rau lub hauv paus hlau atom lossis ion ntawm ob lub ntsiab lus. Piv txwv ntawm bidentate ligands yog ethylenediamine (en), thiab oxalate ion (ox).
txhais li cas los ntawm bidentate?
1: muaj ob tug hniav los yog ob txoj kev qhia ntawm cov hniav.
txhais tau li cas los ntawm bidentate ligand muab ob qho piv txwv?
Bidentate ligand:
Ob qhov chaw pub dawb tam sim no. Piv txwv suav nrog ethylene diammine thiab oxalate ion.
txhais li cas los ntawm bidentate thiab Ambidentate ligands?
Didentate ligands: Ligands uas muaj ob qhov chaw pub dawb hu ua Didentate ligands. Piv txwv li, 1) Ethane-1, 2-diamine. 2) Oxalate ion. Ambidentate ligands: Ligands uas tuaj yeem txuas lawv tus kheej mus rau hauv nruab nrab hlau atom los ntawm ob lub atoms sib txawv hu ua ambidentate ligands.
