Cov pa roj carbon Forms Covalent Bonds

Piv txwv ntawm covalent bonds tsim los ntawm carbon suav nrog carbon - carbon , carbon -hydrogen, thiab carbon - oxygen bonds. Piv txwv ntawm tshuaj sib xyaw uas muaj cov ntawv cog lus no suav nrog methane, dej, thiab carbon dioxide.

Tsis tas li lo lus nug yog, dab tsi cov tebchaw tsim los ntawm carbon?

Qee qhov feem ntau carbon compounds yog: carbon dioxide (CO2), carbon monoxide (CO), carbon disulfide (CS2), chloroform (CHCl3), carbon tetrachloride (CCl4), methane (CH4), ethylene (C2H4), acetylene (C2H2), benzene (C6H6), ethyl cawv (C2H5OH) thiab acetic acid (CH3COV).

Ib yam li ntawd, dab tsi yog ua los ntawm carbon? Saib ncig koj – carbon yog nyob txhua qhov chaw. Koj yog ua ib feem ntawm carbon , yog li ntawd yog khaub ncaws, rooj tog zaum, yas thiab koj cov tshuab hauv tsev. Muaj carbon hauv huab cua peb ua pa. Pob zeb diamond thiab graphite kuj yog ua ntawm carbon.

Ua raws li qhov no hauv kev txiav txim siab, dab tsi 4 organic compounds yog carbon pom nyob rau hauv?

Cov pa roj carbon monoxide yog qhov tshwj xeeb ntawm lwm cov ntsiab lus vim tias nws tuaj yeem sib txuas hauv txoj hauv kev tsis muaj kev txwv nrog cov ntsiab lus xws li hydrogen, oxygen, nitrogen, sulfur thiab lwm yam carbon atoms. Txhua yam nyob ib leeg xav tau plaub hom organic tebchaw kom ciaj sia - carbohydrates , lipids , nucleic acids thiab cov proteins.

Dab tsi yog 4 hom kev sib cog lus carbon tuaj yeem tsim tau?

Carbon tuaj yeem tsim ib leeg daim ntawv cog lus (kev sib koom ntawm 2 electrons), ob npaug daim ntawv cog lus (share of 4 electrons), thiab/los yog triple daim ntawv cog lus (kev sib koom ntawm 6 electrons).
