2 sigma daim ntawv cog lus
Hais txog qhov no, dab tsi atomic lossis hybrid orbitals ua kom muaj kev sib raug zoo ntawm C thiab O hauv carbon dioxide co2?
Piv txwv li, ib tug molecule ntawm carbon dioxide muaj ob npaug daim ntawv cog lus . Cov molecule tuaj yeem sawv cev ua O = C = O , qhov twg oxygen atom tsim ob daim ntawv cog lus nrog lub hauv paus carbon . Cov carbon atom hauv CO2 muaj ob npaug daim ntawv cog lus , ib co atom ntawm oxygen . Yog li ntawd, lub carbon hybridization yog sp.
Tsis tas li ntawd, hom kev sib txuas ntawm cov pa roj carbon thiab oxygen hauv co2 yog dab tsi? Cov carbon dioxide molecule yog tsim los ntawm ib tug carbon atom thiab ob lub oxygen. Raws li ib feem, carbon tsuas muaj 4 lub plhaub sab nrauv electrons thiab oxygen 6. Ob npaug covalent bonds tsim ntawm cov atoms, qhov twg ob electrons los ntawm txhua lub atom sib koom ua 4 kev sib raug zoo electrons nyob rau hauv tag nrho.
Ib sab saum toj no, pes tsawg daim ntawv cog lus carbon dioxide muaj?
plaub
Co2 muaj pes tsawg leeg?
Yog li txhua Oxygen muaj ob khub ntawm unbinding electrons thiab muaj 2 Oxygen atoms nyob rau hauv lub CO2 molecule. Qhov no ua rau tag nrho plaub khub ntawm unbonded electrons.

Yuav ua li cas yog daim ntawv cog lus sib txawv ntawm daim ntawv cog lus ionic?
Qhov sib txawv ntawm cov ionic thiab covalent daim ntawv cog lus yog tias covalent daim ntawv cog lus yog tsim thaum ob lub atoms sib koom electrons. Ionic bonds yog lub zog uas tuav ua ke electrostatic zog ntawm kev nyiam ntawm cov ions oppositely them. Ionic bonds muaj qhov sib txawv electronegativity ntau dua lossis sib npaug li 2
Dab tsi yog qhov txawv ntawm daim ntawv cog lus lub zog thiab daim ntawv cog lus dissociation zog?
Qhov sib txawv tseem ceeb ntawm kev sib txuas ntawm lub zog thiab lub zog bonddissociation yog tias lub zog sib txuas yog qhov nruab nrab ntawm lub zog xav tau los rhuav tshem tag nrho cov kev sib txuas ntawm tib ob hom atoms nyob rau hauv ib qho chaw sib txuas whereas daim ntawv cog lus dissociation zog yog tus nqi ntawm cov hluav taws xob xav tau los rhuav tshem ib qho kev sib koom ua ke inhomolysis
Puas yog daim ntawv cog lus hydrogen zoo ib yam li daim ntawv cog lus?
Hydrogen daim ntawv cog lus yog lub npe muab rau electrostatic kev sib cuam tshuam ntawm tus nqi zoo ntawm hydrogen atom thiab tus nqi tsis zoo ntawm oxygen atom ntawm ib qho chaw nyob sib ze. Covalent daim ntawv cog lus yog qhov sib cuam tshuam electrostatic ntawm ob lub atom hauv tib lub molecule
Muaj pes tsawg daim ntawv cog lus tuaj yeem tsim carbon atom thiab vim li cas?
plaub Tsis tas li ntawd, vim li cas nws tseem ceeb uas cov pa roj carbon tsim 4 daim ntawv cog lus? Cov pa roj carbon yog tib lub ntsiab uas ua tau daim ntawv thiaj li sib txawv tebchaw vim txhua carbon atom tau daim ntawv plaub tshuaj daim ntawv cog lus rau lwm cov atoms, thiab vim cov carbon atom tsuas yog txoj cai, me me kom haum rau qhov yooj yim raws li qhov chaw ntawm cov molecules loj heev.
Muaj pes tsawg tus electrons raug muab faib rau hauv ob daim ntawv cog lus?
Hauv daim ntawv cog lus covalent ib khub ntawm electrons tau sib koom ntawm ob lub atoms 'txuas' los ntawm covalent daim ntawv cog lus. Yog li ib daim ntawv cog lus doublecovalent muaj ob khub ntawm electrons raug muab sib koom, yog li tag nrho plaub electrons
