Qhov sib txawv tseem ceeb ntawm kev sib tw siab thiab qis spin complexes yog qhov siab spin complexes muaj cov tsis muaj electrons, whereas low spin complexes yuav muaj khub electrons.
Cov ntsiab lus siab tig thiab qis qis yog cuam tshuam nrog kev sib koom ua ke. Cov no yog hu ua spin states of complexes. Peb tuaj yeem txiav txim siab cov xeev no siv cov kev tshawb xav siv lead ua teb thiab ligand field theory. Feem ntau, octahedral complexes thiab tetrahedral complexes yog siab spin, thaum square planar complexes tsis tshua muaj kiv.
High Spin Complexes yog dab tsi?
High spin complexes yog kev sib koom ua ke uas muaj cov hluav taws xob tsis sib xws ntawm qib siab zog. Txij li thaum lawv muaj unpaired electrons, cov high spin complexes yog paramagnetic complexes. Qhov no txhais tau hais tias cov complexes tuaj yeem nyiam mus rau qhov chaw sib nqus sab nraud.
Daim duab 01: Lub Zog Sib Nqus Daim Duab rau Kev Sib Tw Siab Siab
Ib lub zog loj spinning ntawm ib qho kev sib txuas tshwm sim thaum lub zog xav tau los ua ke ob lub tshuab hluav taws xob ntau dua li lub zog xav tau los tso hluav taws xob hauv lub zog siab. Feem ntau, octahedral thiab tetrahedral coordination complexes yog siab spin complexes.
Dab tsi yog qhov qis qis qis?
Low spin complexes yog kev sib koom ua ke uas muaj cov khoom siv hluav taws xob sib txuas ntawm qib qis zog. Txij li thaum tsis muaj cov hluav taws xob tsis sib xws hauv cov tshuab qis qis (tag nrho cov electrons yog khub), lawv yog diamagnetic. Qhov no txhais tau tias cov tebchaw no tsis tuaj yeem nyiam mus rau qhov chaw sib nqus sab nraud. Lub zog qis ntawm qhov sib xyaw ua ke tshwm sim thaum lub zog xav tau los ua ke ob lub tshuab hluav taws xob qis dua li lub zog xav tau los tso cov hluav taws xob hauv lub xeev qis. Feem ntau, square planar coordination complexes yog tsawg spin complexes.
Daim duab 02: Lub Zog Sib Nqus Daim Duab Sib Nrauj rau Tsawg Sib Tw
Yuav kom txiav txim siab seb qhov kev sib koom ua ke muab kev sib koom ua ke yog qhov sib tw siab lossis qhov tsis tshua muaj kiv, peb tuaj yeem siv cov lus qhia hauv qab no.
- Kev txiav txim siab ntawm cov duab ntawm qhov complex
- Kev txiav txim siab ntawm lub xeev oxidation ntawm lub chaw hlau
- Kev txiav txim siab ntawm d electron teeb tsa ntawm cov hlau
- Kev txiav txim siab ntawm daim duab siv lead ua ntawm lub complex hais txog nws cov geometry
- Kev txiav txim siab seb lub zog sib cais yog siab dua li lub zog ua khub
Dab tsi yog qhov sib txawv ntawm High Spin thiab Low Spin Complexes?
Qhov sib txawv tseem ceeb ntawm kev sib tw siab thiab qis spin complexes yog qhov siab spin complexes muaj cov tsis muaj electrons, whereas low spin complexes yuav muaj khub electrons. Nyob rau hauv high spin complexes, lub zog yuav tsum tau ua ke li ob lub electrons yog ntau dua li lub zog yuav tsum tau tso ib tug electron ntawm lub complex nyob rau hauv ib tug siab zog theem. Nyob rau hauv sib piv, nyob rau hauv tsawg spin complexes, lub zog yuav tsum tau rau khub ob electrons yog qis dua lub zog yuav tsum tau muab ib tug electron nyob rau hauv ib tug siab zog theem.
Tsis tas li ntawd, lwm qhov sib txawv tseem ceeb ntawm qhov siab spin thiab qis spin complexes yog qhov siab spin complexes yog paramagnetic vim lawv muaj unpaired electrons, tab sis tsawg spin complexes yog diamagnetic vim lawv muaj tag nrho cov electrons ua ke. Feem ntau, cov tetrahedral thiab octahedral tebchaw yog siab spin thaum square planar tebchaw yog tsawg spin.
Summary – High Spin vs Low Spin Complexes
Muaj ob hom kev sib tw ntawm lub xeev kev sib koom ua ke. Cov no yog lub xeev siab spin thiab lub xeev qis spin. Qhov sib txawv tseem ceeb ntawm high spin thiab low spin complexes yog cov high spin complexes muaj unpaired electrons, whereas low spin complexes yuav muaj khub electrons.
