Nws yog vim catenation uas carbon cov ntaub ntawv ib loj tus naj npawb ntawm cov khoom xyaw . Cov pa roj carbon muaj plaub electrons hauv nws lub plhaub valence. Cov pa roj carbon , siv plaub valence electrons, muaj peev xwm daim ntawv ntau daim ntawv cog lus i.e ob npaug thiab triple. Qhov no kuj yog tus vim li cas rau lub hav zoov loj tus lej ntawm carbon compounds.

Ib sab ntawm qhov no, dab tsi yog vim li cas tseem ceeb rau ntau cov organic tebchaw?

Lub neej ntawm xws li ib ntau cov organic tebchaw yog vim li no vim li cas : (i) Ib vim li cas rau lub neej ntawm a ntau cov organic tebchaw yog tias cov pa roj carbon atoms tuaj yeem txuas nrog ib leeg los ntawm kev sib koom ua ke los tsim cov saw ntev lossis cov nplhaib ntawm cov pa roj carbon atom.

Qhov thib ob, vim li cas qee qhov ntawm cov no hu ua saturated thiab lwm yam unsaturated compounds? Saturated hydrocarbons tsuas muaj sigma daim ntawv cog lus, uas ruaj khov thiab nyuaj rau tawg. Txawm li cas los xij, unsaturated hydrocarbons muaj pi bonds thiab lawv tsis muaj zog. Yog li ntawd, electrons yuav yooj yim muaj nyob rau hauv unsaturated compounds ua rau nws reactive ntau dua saturated compounds.

Hais txog qhov no, vim li cas cov pa roj carbon feem ntau nyob hauv lub xeev ua ke?

Cov pa roj carbon atoms yog cov tshuaj reactive heev, thiab muaj lub siab xav qhia electrons nrog rau lwm cov atom txaus siab rau ua yog li, nrog rau lwm yam carbon atoms.

Vim li cas carbon thiaj pom nyob rau hauv txhua yam muaj sia?

Txhua yam muaj sia muaj carbon nyob rau hauv ib co qauv. Cov pa roj carbon Nws yog ib qho tseem ceeb ntawm macromolecules, suav nrog cov protein, lipids, nucleic acids, thiab carbohydrates. Cov pa roj carbon Cov qauv molecular tso cai rau nws sib txuas hauv ntau txoj kev sib txawv thiab nrog ntau yam sib txawv.
