Kev siv ntau tshaj ntawm ethane yog tsim ethene los ntawm cov txheej txheem tawg. Tsis tas li ntawd, ethane yog cov tub yees siv rau hauv cov tub yees txias txias.
Ethene yog dab tsi?
Ethene yog ib qho organic compound uas muaj cov tshuaj formula C2H4 Lub npe ntawm cov tshuaj no yog ethylene. Muaj ob daim ntawv cog lus ntawm ob lub atoms: sigma daim ntawv cog lus thiab ib daim ntawv cog lus pi. Yog li ntawd, hybridization ntawm carbon atoms nyob rau hauv no molecule yog sp2 hybridization. Yog li, lub geometry nyob ib ncig ntawm ib tug carbon atom yog planar, thiab muaj un-hybridized p orbitals nyob rau hauv carbon atoms. Qhov no ua rau tag nrho cov molecule ib tug planar molecule. Txij li thaum muaj ob daim ntawv cog lus, ethene yog ib qho molecule unsaturated.
Daim duab 2: Cov Qauv Tshuaj ntawm Ethene
Qee Cov Lus Tseeb Txog Ethene
- Chemical formula=C2H4.
- Molar mass=28.05 g/mol
- Lub cev lub cev ntawm chav tsev kub=tsis muaj xim, cov pa taws kub hnyiab
- Suab=tus yam ntxwv qab zib
- melting point=-169.2 °C
- Boiling point=−103.7°C
Qhov ob daim ntawv cog lus tam sim no nyob rau hauv cov molecule no ua rau cov reactivity ntawm cov compound no. Tsis tas li ntawd, ethene yog siv los ua ib qho monomer rau kev tsim cov polymers xws li polyethylene los ntawm kev ntxiv polymerization. Tsis tas li ntawd, ethene yog cov tshuaj cog qoob loo uas tuaj yeem tswj cov txiv hmab txiv ntoo ripening.
Ethyne yog dab tsi?
Ethyne yog ib qho organic compound uas muaj cov tshuaj formula C2H2 Lub npe ntawm cov tshuaj no yog acetylene. Nws muaj peb daim ntawv cog lus ntawm ob lub atoms: ib sigma daim ntawv cog lus thiab ob daim ntawv cog lus pi. Yog li ntawd tsis muaj un-hybridized p orbitals nyob rau hauv cov carbon atoms. Txhua cov pa roj carbon atom muaj ib qho hydrogen atom sib txuas ntawm ib daim ntawv cog lus. Lub geometry ntawm cov molecule yog linear, thiab cov qauv yog planar.
Daim duab 3: Cov Qauv Tshuaj ntawm Ethyne
Qee Cov Lus Tseeb Txog Ethylene
- Chemical formula=C2H2.
- Molar mass=26.04 g/mol
- Lub cev lub cev ntawm chav tsev kub=tsis muaj xim, cov pa taws kub hnyiab
- Sau=tsis muaj ntxhiab
- Melting point=−80.8 °C (triple point of acetylene)
- Boiling point=−84°C (sublimation point)
Thaum ntxov, ethyl yog tsim los ntawm ib nrab combustion ntawm methane. Cov txheej txheem yooj yim tshaj plaws ntawm kev tsim cov ethyl yog los ntawm cov tshuaj tiv thaiv ntawm calcium carbide thiab dej. Cov khoom ntawm cov tshuaj tiv thaiv no yog ethylene gas thiab calcium carbonate. Tab sis, qhov no yog qhov nyuaj hauv cov ntawv thov kev lag luam vim tias qhov no xav tau qhov kub thiab txias. Yog li ntawd, peb siv cov txheej txheem hauv qab no hauv kev tsim khoom lag luam ntawm ethyl:
- Kev tsim cov ethyl siv calcium carbide raws li kev tswj hwm
- Thermal tawg ntawm hydrocarbons
Qhov Zoo sib xws ntawm Ethane Ethene thiab Ethyne yog dab tsi?
- Ethane Ethene thiab Ethyne yog hydrocarbon compounds
- Ethane Ethene thiab Ethyne yog cov pa roj ntawm chav tsev kub.
- Tag nrho peb suav nrog ob lub atoms.
