Cov pa roj carbon yog tus xwb keeb uas tau form ntau heev txawv tshuaj sib xyaw vim cwb carbon atom tau daim ntawv plaub chemical bonds rau lwm cov atoms, thiab vim hais tias cov carbon atom tsuas yog txoj cai, me me kom haum rau qhov yooj yim raws li qhov chaw ntawm cov molecules loj heev.

Yog li ntawd, dab tsi yog qhov tseem ceeb carbon compound piav?

Cov tshuaj ntawm carbon yog txhais raws li chemical tshuaj muaj carbon . Ntau tshuaj sib xyaw ntawm carbon muaj ntau dua li lwm yam tshuaj lom neeg tshwj tsis yog hydrogen. Ib carbon tseem ceeb vaj tse yog catenation raws li lub peev xwm los tsim ntev carbon chains thiab rings.

Qhov thib ob, vim li cas cov pa roj carbon atoms muaj peev xwm los ua cov ceg thiab tsim cov saw hlau? Qhov no yeej txhais tau tias carbon muaj plaub valence electrons (sab nraud electrons uas yog muaj nyob rau tsim daim ntawv cog lus nrog rau lwm yam atoms ). Cov carbon atom kuj muaj peev xwm rau daim ntawv kev sib raug zoo nrog lwm tus carbon atoms los tsim covalent bonds ua cov hlua ntev ntawm carbon atoms , sib txuas ua ke zoo li kev sib txuas hauv ib saw hlau.

Tsis tas li lo lus nug yog, dab tsi yog 4 yam khoom tshwj xeeb ntawm carbon?

Cov yam ntxwv ntawm carbon suav nrog nws lub 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 bonds nrog lwm cov atoms.

Vim li cas cov pa roj carbon monoxide yog tetravalent keeb?

Lub valence ntawm ib keeb yog qhov siab tshaj plaws ntawm hydrogen lossis chlorine atoms uas tuaj yeem ua ke nrog ib qho atom ntawm cov keeb . Cov pa roj carbon yog nyob rau hauv pawg 14 ntawm Lub Sijhawm Table, yog li a carbon atom muaj plaub valence electrons. Nws tuaj yeem txuas nrog plaub atoms ntawm chlorine. Lub prefix tetra- txhais tau tias plaub, yog li ntawd carbon yog tetravalent.
