Qhov sib txawv tseem ceeb ntawm ethylene thiab ethylidene yog tias ethylene yog ib qho tshuaj nruab nrab, hos ethylidene yog divalent radical compound.
Ethylidene radical cov ntaub ntawv los ntawm ethylene molecules los ntawm kev hloov ntawm cov molecules; Cov ethylene molecule muaj ob lub carbon atoms sib koom ua ke ntawm ob daim ntawv cog lus, thiab muaj ob lub hydrogen atoms txuas rau txhua lub atom. Ethylidene radical, ntawm qhov tod tes, muaj ob lub carbon atoms sib koom ua ke ntawm ib daim ntawv cog lus thiab muaj peb lub atoms hydrogen txuas rau ib lub atom thiab hydrogen atom txuas rau lwm cov pa roj carbon. Yog li ntawd, lub thib ob carbon atom muaj ob unpaired electrons.
Ethylene yog dab tsi?
Ethylene yog cov organic compound uas muaj cov tshuaj formula C2H4. Muaj ob lub carbon atoms sib koom ua ke ntawm ob daim ntawv cog lus (pib daim ntawv cog lus thiab sigma daim ntawv cog lus). Yog li ntawd, ethylene molecule muaj ob sp2 hybridized carbon atoms. Txij li thaum cov pa roj carbon atom muaj peev xwm tsim tau plaub daim ntawv cog lus, muaj ob lub hydrogen atoms sib koom ua ke rau txhua cov pa roj carbon atom ntawm ib daim ntawv cog lus. Li no, cov ethylene molecule muaj cov qauv qauv.
Daim duab 01: Polymerization ntawm Ethylene
Qee cov lus tseeb txog ethylene yog raws li hauv qab no:
- tshuaj formula=C2H4
- Molar mass=28.05 g/mol
- Lub cev lub cev nyob rau hauv chav tsev kub=nws yog xim tsis muaj xim, nplaim hluav taws kub
- Odour=tsw qab
- Melting point=−169.2°C
- Boiling point=−103.7°C
- Solubility hauv dej=me ntsis soluble
- IUPAC lub npe=Ethene
Qhov loj ntawm ethylene yog cov roj av thiab cov nkev ntuj. Muaj peb txheej txheem tseem ceeb siv los tsim ethylene los ntawm cov peev txheej no. Lawv yog,
- Chav tawg ntawm ethane thiab propane
- Neev tawg ntawm naphtha
- Catalytic tawg ntawm cov roj roj
Ethylene tseem ceeb li monomers rau kev tsim cov polymers xws li polyethylene los ntawm kev ntxiv polymerization. Polyethylene yog cov khoom ntim khoom siv. Tsis tas li ntawd, nyob rau hauv cov kab mob lom, ethylene yog ib qho tseem ceeb raws li cov tshuaj hormones cog vim nws txhawb nqa cov txiv hmab txiv ntoo ripening.
YEthylidene yog dab tsi?
Ethylidene yog ib qho radical uas muaj cov tshuaj formula CH3-CH: Qhov no yog divalent radical vim nws muaj ob lub electrons unpaired. Ethylidene radical tuaj yeem npaj tau los ntawm kev tshem tawm ob lub atoms hydrogen los ntawm tib lub atom ntawm ethane. Ntxiv mus, ethylidene radical kuj tuaj yeem tsim tau thaum muaj kev hloov pauv ntawm cov atoms tshwm sim hauv ethylene molecule.
Kev sib raug zoo ntawm Ethylene thiab Ethylidene yog dab tsi?
- Ethylene thiab ethylidene yog cov tshuaj lom neeg cov tshuaj lom neeg.
- Ethylidene radicals yog tsim los ntawm ethylene molecules.
Qhov txawv ntawm Ethylene thiab Ethylidene yog dab tsi?
Ethylene yog cov organic compound uas muaj cov tshuaj formula C2H4 thaum ethylidene yog ib qho radical uas muaj cov tshuaj formula CH3-CH: Qhov sib txawv tseem ceeb ntawm ethylene thiab ethylidene yog ethylene yog ib qho tshuaj nruab nrab, whereas ethylidene yog divalent radical. compound. Ntxiv mus, ethylidene tuaj yeem npaj tau los ntawm kev tshem tawm ob lub atoms hydrogen los ntawm tib lub atom ntawm ethane. Ethylene, ntawm qhov tod tes, tuaj yeem npaj tshuaj los ntawm cov txheej txheem ethanol dehydrogenation.
Cov infographic hauv qab no piv ob lub tebchaw thiab tabulates qhov sib txawv ntawm ethylene thiab ethylidene ib sab.
Summary – Ethylene vs Ethylidene
Nyob rau hauv lub ntsiab lus, ethylene thiab ethylidene yog cov organic tshuaj lom neeg. Ethylidene tuaj yeem npaj tau los ntawm kev tshem tawm ob lub atoms hydrogen los ntawm tib lub atom ntawm ethane. Qhov sib txawv tseem ceeb ntawm ethylene thiab ethylidene yog tias ethylene yog ib qho tshuaj nruab nrab, qhov ethylidene yog divalent radical compound.
