Qhov kev ruaj ntseg ntawm resonance nce nrog: Tus naj npawb ntawm covalent daim ntawv cog lus Tus naj npawb ntawm atoms nrog octet ntawm electrons (tshwj tsis yog hydrogen uas muaj ib qho duplex) … Tus nqi tsis zoo yog tias muaj nyob rau ntawm lub atom ntau electronegative, tus nqi zoo yog tias muaj ntawm cov atom ntau electropositive, ua rau muaj kev ruaj ntseg ntawm atom.
Dab tsi ua rau cov qauv resonance ruaj khov?
Cov qauv resonance nyob rau hauv uas txhua lub atoms muaj tiav valence shells yog ruaj khov dua. Qhov no txhais tau tias feem ntau cov atoms muaj tag nrho octet. … Cov qauv uas muaj tus nqi tsis zoo ntawm lub atom electronegative yuav ruaj khov dua. Qhov sib txawv ntawm ob lub qauv resonance yog qhov kev tso kawm ntawm qhov tsis zoo.
Vim li cas resonance ruaj khov?
Vim resonance tso cai rau delocalization, nyob rau hauv uas tag nrho lub zog ntawm ib lub molecule yog qis dua vim nws cov electrons nyob ib tug ntau dua ntim, molecules uas muaj resonance yog ruaj khov dua cov uas ua. tsis yog. Cov molecules no hu ua resonance stabilized.
Cov qauv resonance twg ruaj khov thiab yog vim li cas?
Qhov tseeb, daim ntawv ruaj khov tshaj plaws yog lub resonance hybridvim nws delocalizes cov electron ceev tshaj tus naj npawb ntawm cov atoms: Txawm li cas los xij, kos cov resonance hybrid tsis yog qhov ua tau zoo heev. thiab feem ntau, qee yam khoom thiab kev cuam tshuam ntawm cov molecule tau piav qhia zoo dua los ntawm ib daim ntawv resonance.
Tus qauv resonating ruaj khov tshaj yog dab tsi?
Cov qauv uas txhua lub atoms muaj lub plhaub valence ntawm electrons (piv txwv li, octet) ruaj khov dua. Ntawm cov kev xaiv C thiab D, kev xaiv D yog qhov ruaj khov dua vim tias cov nqi zoo yog ruaj khov ntawm nitrogen dua li cov pa atom.
