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. Qhia hauv qab no yog daim duab ntawm ethylenediamine : cov nitrogen (xiav) atoms ntawm cov npoo txhua tus muaj ob lub electrons dawb uas tuaj yeem siv los txuas rau lub hauv paus hlau atom lossis ion.

Hais txog qhov no, puas yog ethylenediamine bidentate ligand?

bidentatni ua ligand Bidentate ligand yog a ligand uas muaj ob "cov hniav" los yog atoms uas ncaj qha mus rau lub hauv paus atom nyob rau hauv ib tug complex. Ib qho piv txwv ntawm a bidentate ligand yog ethylenediamine . Ib qho molecule ntawm ethylenediamine tuaj yeem tsim ob daim ntawv cog lus rau cov hlau ion.

Qhov thib ob, tus nqi ntawm ethylenediamine yog dab tsi? · Txij li thaum nws yuav siv 3 sulfates rau daim ntawv cog lus nrog ob complex cations, lub nqi ntawm txhua qhov complex cation yuav tsum yog +3. · Txij li thaum ethylenediamine yog ib qho nruab nrab molecule, oxidation tooj ntawm cobalt nyob rau hauv lub complex ion yuav tsum yog +3.

Ib yam li ntawd, tib neeg nug, hom ligand yog ethylenediamine?

Ethylenediamine yog ib tug paub zoo bidentate chelating ligand rau kev sib koom ua ke, nrog rau ob lub nitrogen atoms pub lawv ib leeg khub ntawm electrons thaum ethylenediamine ua a ligand . Nws yog feem ntau abbreviated "en" nyob rau hauv inorganic chemistry.

Vim li cas dej tsis yog bidentate ligand?

Vim li cas dej yog monodentate, Txawm hais tias nws muaj ob leeg ib leeg tsis yog ib qho. Rau ib ligand yuav monodentate nws yuav tsum muaj ib leeg ib khub? Vim hais tias ntawm Orbital geometry, tsuas yog ib leeg ib leeg tuaj yeem muaj qhov tseeb kev taw qhia rau 'kev sib raug zoo' (lwm tus yuav taw tes tawm ntawm lub hauv paus atom). yog li nws unidentate.
