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.

Ib sab saum toj no, ua li cas carbon atoms tsim ntau lub tebchaw? Hauv tshuaj sib xyaw , carbon atoms ib txwm qhia plaub khub ntawm electrons hauv plaub covalent bonds. Qhov no txhais tau tias ib tug carbon atom ua tau daim ntawv ib daim ntawv cog lus nrog mus txog plaub lwm atoms . Cov pa roj carbon atoms kuj daim ntawv ntau daim ntawv cog lus nrog lwm tus atoms suav nrog lwm yam carbon atoms.

Tsis tas li ntawd, hom ntawv cog lus twg yog cov pa roj carbon atom tsim?

Covalent Bonds

Muaj pes tsawg covalent bonds tuaj yeem tsim cov pa roj carbon thiab vim li cas qhov no tseem ceeb hauv kev tsim cov roj ntsha molecules?

plaub covalent bonds

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 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
