Cov bond dissociation zog los yog, ntau dua, homolytic bond dissociation zog (Symbol: BDE) ntawm acovalent daim ntawv cog lus yog lub zog yuav tsum tau rhuav lub daim ntawv cog lus homolytically (saib homolysis) raws li tus qauv. Cov siab dua tus bond dissociation zog , lub zog daim ntawv cog lus.

Tsis tas li ntawd, daim ntawv cog lus dissociation zog txhais li cas?

Bond dissociation zog yog cov zog yuav tsum tau rhuav ib qho tshuaj daim ntawv cog lus . Nws yog ib qho txhais tau tias ofquantifying lub zog ntawm ib tug tshuaj daim ntawv cog lus . Bonddissociation zog sib npaug daim ntawv cog lus zog tsuas yog rau diatomicmolecules. Lub zog tshaj bond dissociation zog yog rau Si-F daim ntawv cog lus.

Tsis tas li ntawd, homolytic bond dissociation zog yog dab tsi? Cov homolytic bond dissociation zog yog tus nqi ntawm zog yuav tsum tau sib cais ib mole ntawm covalently bonded gases rau hauv ib khub ntawm radicals. Cov chav SI siv los piav qhia daim ntawv cog lus zog yog kiloJoules ib mole ntawm daim ntawv cog lus (kJ/Mol). Nws qhia tau hais tias cov atoms muaj zog npaum li cas rau ib leeg.

Ua raws li qhov no hauv kev xav, dab tsi yog daim ntawv cog lus siab dissociation enthalpy?

A high bond dissociation zog txhais tau tias cov daim ntawv cog lus (thiab molecule) yog tsawg zog thiab ruaj khov. Bond lub zog nyob ntawm tus naj npawb ntawm daim ntawv cog lus nruab nrab ntawm atoms. Txawm tias π daim ntawv cog lus tsis muaj zog tshaj σ daim ntawv cog lus ,ib ob daim ntawv cog lus , uas muaj σ thiab π yog daim ntawv cog lus , muaj zog tshaj ib leeg daim ntawv cog lus vim muaj ob daim ntawv cog lus.

Dab tsi yog lub cim rau daim ntawv cog lus dissociation zog?

Cov bond dissociation zog los yog, ntau dua, homolytic bond dissociation zog ( cim : BDE) ntawm acovalent daim ntawv cog lus yog cov zog yuav tsum tau rhuav lub daim ntawv cog lus homolytically (saib homolysis) raws li tus qauv. eg. 1: np. 2: Ua bond dissociation zog ntawm a daim ntawv cog lus yog qhov ntsuas ntawm nws lub zog.
