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.

Vim li cas cov pa roj carbon ntau tshaj ntawm cov tebchaw muab ob qho laj thawj?
Nws yog vim catenation uas carbon tsim ib tug loj tus naj npawb ntawm cov tebchaw. Cov pa roj carbon muaj plaub electrons hauv nws lub plhaub valence. Carbon, siv plaub valence electrons, muaj peev xwm tsim ntau daim ntawv cog lus xws li ob npaug thiab triple. Qhov no kuj yog vim li cas rau lub hav zoov ntawm cov pa roj carbon ntau
Cov organic tebchaw tau txais lawv lub npe Li cas lo lus muaj feem xyuam rau nws lub ntsiab lus li cas?
Lo lus hais txog nws lub ntsiab lus li cas? Organic Compounds tau txais nws lub npe los ntawm tus lej ntawm cov ntawv cog lus carbon. Lo lus muaj feem xyuam rau lub ntsiab lus vim hais tias nws yuav tsum tau ua nrog bonds nyob rau hauv carbon atoms nyob rau hauv cov organic tebchaw
Cov nqe lus twg zoo tshaj plaws piav qhia txog qhov tseem ceeb ntawm cov lus qhia muaj nuj nqis?
Qhov tsis suav nrog tus nqi ntawm ib qho kev qhia rational yog qhov tseem ceeb uas tus denominator ntawm qhov kev qhia yog xoom. Tsis tas li ntawd, tus naj npawb ntawm zeros ntawm ib tug polynomial yeej ib txwm tsawg dua los yog sib npaug rau degree ntawm lub polynomial. Yog li ntawd, tus naj npawb ntawm cov txiaj ntsig tsis suav nrog cov lus qhia muaj txiaj ntsig tsis tuaj yeem tshaj li qib ntawm tus lej
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
Cov nqe lus twg muaj tseeb txog cov cell hauv ntau cov kab mob?
Teb: A) Cov hlwb muaj cov noob sib txawv thiab yog li qhia cov noob sib txawv. Kev piav qhia: Hauv ntau cov kab mob, cov hlwb muaj cov noob sib txawv thiab yog li qhia cov noob sib txawv
