Kom saib seb lub ligand yog bidentate, tridentate, los yog hexadentate, koj saib seb muaj pes tsawg tus khub muaj ib qho sib txawv atoms . Txoj hauv kev zoo tshaj plaws los pom qhov no yog los ntawm kev kos ib tus qauv lewis qauv Lewis qauv tau muab npe tom qab Gilbert N. Lewis, uas tau qhia nws hauv nws xyoo 1916 tsab xov xwm Lub Atom thiab Molecule. Cov qauv Lewis txuas ntxiv lub tswv yim ntawm daim duab duab hluav taws xob los ntawm kev ntxiv cov kab nruab nrab ntawm cov atoms los sawv cev rau cov khub sib koom hauv cov ntawv cog lus tshuaj. https://en.wikipedia.org › wiki › Lewis_structure

. Piv txwv li, tus bidentate yuav muaj ob leeg ib leeg, txhua tus ntawm cov atom sib txawv.
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).
Koj paub li cas lub ligand atom ntawm ib lub atom?
Tus pub atom yog atom hauv ligand uas txuas nrog Lewis acid centre. Tus naj npawb ntawm kev sib koom tes yog tus naj npawb ntawm cov neeg pub dawb atom hauv kev sib koom ua ke. Lub denticity ntawm ib lub ligand yog tus naj npawb ntawm daim ntawv cog lus uas nws tsim nrog Lewis acid centre.
Nws yog bidentate thiab negative ligand?
Acetato is monodentate ligand.
Puas yog BR yog bidentate ligand?
Option (b) i.e. (C2O4)2- yog tuskev xaiv raug raws li nws muaj ob tus neeg pub dawb atoms thiab vim qhov no lub ligand (C2O4) 2- muaj peev xwm ntawm kev sib txuas rau hauv nruab nrab atom los ntawm ob lub atoms pub dawb thiab yog li nws tau hais tias yog bidentate ligand raws li peb paub tias bidentate ligand yog ib ligand hauv uas muaj yog ob pawg pub dawb / atom …
