Qhov sib txawv tseem ceeb ntawm homolytic thiab heterolytic fission yog tias homolytic fission muab ib daim ntawv cog lus electron rau txhua qhov tawg thaum lub heterolytic fission muab ob daim ntawv cog lus electrons rau ib feem thiab tsis muaj daim ntawv cog lus electrons rau lwm qhov.

Fission yog kev puas tsuaj ntawm covalent chemical bond. Hauv lwm lo lus, nws faib ib lub molecule rau hauv ob lub moieties. Fission tuaj nyob rau hauv ob daim ntawv raws li homolytic fission uas ua rau ob qho tib si moieties thiab heterolytic fission uas ua rau ob qho tib si moieties.

Homolytic Fission yog dab tsi?

Homolytic fission yog kev sib cais ntawm cov tshuaj lom neeg thiab tsim ob qhov sib npaug. Ib daim ntawv cog lus tshuaj (covalent bond) muaj ob lub electrons. Nyob rau hauv daim ntawv no ntawm fission, txhua qhov ntawm cov fragments tau txais ib tug unpaired electron. Thaum no daim ntawv cog lus dissociation tshwm sim nyob rau hauv ib tug nruab nrab molecule uas muaj ib tug txawm tus xov tooj ntawm electrons, nws ua ob sib npaug zos, dawb radicals.

Daim duab 01: Homolytic Fission

Homolytic bond dissociation zog yog hais txog lub zog uas yog absorbed los yog tso tawm thaum lub sij hawm tus txheej txheem no. Txawm li cas los xij, qhov kev sib cais no tsuas yog nyob rau hauv cov xwm txheej tshwj xeeb;

Hlub

Ntxiv rau qhov ntawd, qee cov khoom siv tshuaj lom neeg xws li peroxide daim ntawv cog lus tsis muaj zog txaus los cuam tshuam nws tus kheej thaum tshav kub me ntsis.

Heterolytic Fission yog dab tsi?

Heterolytic fission yog kev sib cais ntawm cov tshuaj lom neeg thiab tsim ob qhov tsis sib xws. Ib daim ntawv cog lus tshuaj (covalent bond) muaj ob lub electrons. Nyob rau hauv daim ntawv no ntawm fission, ib feem tau txais ob daim ntawv cog lus electron khub thaum lwm cov fragment tsis tau txais ib qho ntawm cov nyiaj electrons.

Daim duab 02: Heterolytic Fission

Cov tawg uas tau txais ob daim ntawv cog lus electrons tsim ib qho anion. Lwm qhov tawg ua ib qho cation. Nyob ntawd, cov seem uas tau txais ob qho tib si electrons yog ntau electronegative dua li lwm cov khoom tawg. Qhov no fission tshwm sim nyob rau hauv ib tug covalent bonds. Lub zog uas yog absorbed los yog tso tawm thaum lub sij hawm daim ntawv cog lus cleavage no hu ua "heterolytic bond dissociation zog".

Qhov txawv ntawm Homolytic thiab Heterolytic Fission yog dab tsi?

Homolytic fission yog kev sib cais ntawm cov tshuaj lom neeg thiab tsim ob qhov sib npaug. Nws muab ib daim ntawv cog lus electron rau txhua ntu. Lub zog uas yog absorbed los yog tso tawm thaum lub sij hawm homolytic fission yog hu ua "homolytic bond dissociation zog". Heterolytic fission yog dissociation ntawm ib daim ntawv cog lus tshuaj thiab tsim ob qhov tsis sib xws. Nws muab ob daim ntawv cog lus electrons rau ib feem thiab tsis muaj daim ntawv cog lus electrons rau lwm qhov. Qhov no yog qhov sib txawv tseem ceeb ntawm homolytic thiab heterolytic fission. Lub zog uas yog absorbed los yog tso tawm thaum lub sij hawm heterolytic fission yog hu ua "heterolytic bond dissociation zog".

Summary – Homolytic vs Heterolytic Fission

Fission yog daim ntawv cog lus dissociation. Nws yog nyob rau hauv ob daim ntawv ua homolytic thiab heterolytic fission. Qhov txawv ntawm homolytic thiab heterolytic fission yog tias homolytic fission muab ib daim ntawv cog lus electron rau txhua qhov tawg thaum lub heterolytic fission muab ob daim ntawv cog lus electrons rau ib feem thiab tsis muaj daim ntawv cog lus electrons mus rau lwm qhov seem.
