Organic compounds uas muaj carbon-carbon ob daim ntawv cog lus hu ua alkenes . Cov pa roj carbon atoms koom nrog ob daim ntawv cog lus yog sp2 hybridized. Ob qhov yooj yim tshaj plaws alkenes yog ethene (C2H4) thiab propene (C3H6). Alkenes nyob rau hauv uas txoj hauj lwm ntawm ob daim ntawv cog lus sib txawv yog txawv molecules.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi hydrocarbon muaj ob daim ntawv cog lus?
alkenes
Ib tug kuj yuav nug, cov tshuaj twg yog feem ntau yuav ua lub luag hauj lwm rau cov organic molecule coj raws li lub hauv paus? Amino. Amines muaj nitrogen organic puag.
Tsis tas li ntawd paub, hom carbon skeletons tuaj yeem tsim tau?
Lesson Summary Lawv muaj li ntawm carbon - carbon atom uas daim ntawv chains los ua ib qho organic compound. Length, puab, qhov chaw, thiab tus nqi ntawm ob daim ntawv cog lus yog cov yam ntxwv ntawm carbon skeletons . Branched, ncaj saw, los yog rings muaj ntau hom ntawm cov pob txha.
Muaj pes tsawg daim ntawv cog lus tuaj yeem tsim tau carbon?
plaub

Yuav ua li cas yog daim ntawv cog lus sib txawv ntawm daim ntawv cog lus ionic?
Qhov sib txawv ntawm cov ionic thiab covalent daim ntawv cog lus yog tias covalent daim ntawv cog lus yog tsim thaum ob lub atoms sib koom electrons. Ionic bonds yog lub zog uas tuav ua ke electrostatic zog ntawm kev nyiam ntawm cov ions oppositely them. Ionic bonds muaj qhov sib txawv electronegativity ntau dua lossis sib npaug li 2
Dab tsi yog qhov txawv ntawm daim ntawv cog lus lub zog thiab daim ntawv cog lus dissociation zog?
Qhov sib txawv tseem ceeb ntawm kev sib txuas ntawm lub zog thiab lub zog bonddissociation yog tias lub zog sib txuas yog qhov nruab nrab ntawm lub zog xav tau los rhuav tshem tag nrho cov kev sib txuas ntawm tib ob hom atoms nyob rau hauv ib qho chaw sib txuas whereas daim ntawv cog lus dissociation zog yog tus nqi ntawm cov hluav taws xob xav tau los rhuav tshem ib qho kev sib koom ua ke inhomolysis
Puas yog daim ntawv cog lus hydrogen zoo ib yam li daim ntawv cog lus?
Hydrogen daim ntawv cog lus yog lub npe muab rau electrostatic kev sib cuam tshuam ntawm tus nqi zoo ntawm hydrogen atom thiab tus nqi tsis zoo ntawm oxygen atom ntawm ib qho chaw nyob sib ze. Covalent daim ntawv cog lus yog qhov sib cuam tshuam electrostatic ntawm ob lub atom hauv tib lub molecule
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Dab tsi hydrocarbon muaj ob daim ntawv cog lus hauv molecule?
Tej yam yooj yim hydrocarbons thiab lawv variations Number of carbon atoms Alkane (ib daim ntawv cog lus) Alkene (ob daim ntawv cog lus) 1 Methane - 2 Ethane Ethene (ethylene) 3 Propane Propene (propylene) 4 Butane Butene (butylene)
