Carbon Bonding

Vim nws muaj plaub valence electrons, carbon xav tau plaub electrons ntxiv los ua kom nws lub zog sab nraud. Los ntawm kev tsim plaub covalent daim ntawv cog lus , carbon qhia plaub khub ntawm electrons, yog li sau nws cov qib zog sab nraud. A carbon atom ua tau daim ntawv cog lus nrog lwm tus carbon atoms los yog nrog cov atoms ntawm lwm yam.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog 4 hom bonds carbon tuaj yeem tsim?

Muaj plaub yam hom ntawm carbon kev sib txuas : ib zaug, ob npaug, triple thiab aromatic kev sib raug zoo.

Qhov thib ob, pes tsawg daim ntawv cog lus carbon tuaj yeem cuam tshuam rau nws lub peev xwm los tsim cov molecules nrog ntau cov duab sib txawv? Cov pa roj carbon yog lub ntsiab xwb uas tuaj yeem tsim yog li ntawd ntau yam sib txawv compounds vim txhua carbon atom tuaj yeem tsim 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 heev loj molecules.

Hais txog qhov no, hom qauv twg tuaj yeem tsim carbon?

Plaub lub ntsiab daim ntawv ntawm carbon -pob zeb diamond, graphite, buckyballs, thiab CNTs-yog lub tsheb zoo heev rau kev qhia cov hauv paus ntsiab lus ntawm kev sib txuas tshuaj, khoom siv qauv , thiab khoom. Cov pa roj carbon atoms daim ntawv ntau yam cov qauv uas yog intrinsically txuas nrog cov khoom uas lawv nthuav tawm.

Dab tsi yog cov yam ntxwv ntawm carbon atoms?

Cov pa roj carbon Cov yam ntxwv muaj xws li nws muaj peev xwm sib txuas nrog oxygen, hydrogen, nitrogen, phosphorus thiab sulfur. Cov pa roj carbon biochemical compounds yog qhov tseem ceeb rau txhua lub neej hauv ntiaj teb. Vim nws muaj peev xwm sib txuas, carbon tuaj yeem tsim ib qho, ob npaug, lossis triple covalent daim ntawv cog lus nrog lwm tus atoms.
