Qhov sib txawv tseem ceeb ntawm acetylene thiab propane yog tias acetylene muaj triple daim ntawv cog lus ntawm ob lub atoms carbon whereas propane tsis muaj ob lossis triple bonds ntawm carbon atoms uas tsis yog ib daim ntawv cog lus. Txawm hais tias ob lub tebchaw no yog cov pa roj, muaj ntau qhov sib txawv ntawm acetylene thiab propane raws li tau tham hauv tsab xov xwm no kom ntxaws.
Acetylene yog C2H2 , thiab nws lub npe hu ua ethyl. Tsis tas li ntawd, nws yog hydrocarbon thiab yog qhov yooj yim tshaj plaws alkyne uas tshwm sim raws li cov roj tsis muaj xim. Propane yog C3H8, thiab nws ib qho yooj yim alkane uas tsis muaj unsaturation (tsis muaj ob daim ntawv cog lus lossis triple bonds). Nws kuj tshwm sim raws li ib tug gas. Txawm li cas los xij, peb tuaj yeem hloov nws mus ua kua.
Acetylene yog dab tsi?
Acetylene yog qhov yooj yim tshaj plaws alkyne uas muaj cov tshuaj formula C2H2 Lub npe IUPAC lub npe ntawm cov tshuaj no yog ethyl. Tsis tas li ntawd, nws yog cov roj tsis muaj xim nyob rau hauv chav tsev kub thiab siab. Peb tuaj yeem categorize nws li hydrocarbon vim tias nws tsuas muaj cov pa roj carbon thiab hydrogen atoms nrog kev sib txuas ntawm cov pa roj carbon atoms. Peb siv cov roj no dav ua roj thiab lub tsev thaiv rau kev sib txuas ntawm cov tshuaj sib txawv.
Daim duab 01: Cov Qauv Tshuaj ntawm Acetylene
Muaj ib daim ntawv cog lus triple ntawm ob lub pa roj carbon atom ntawm no molecule. Ntxiv mus, qhov valency ntawm ib tug carbon atoms yog 4. Yog li ntawd, txhua carbon atoms khi rau ib hydrogen atom ntawm ib daim ntawv cog lus. Lub molecule muaj ib tug linear geometry, thiab nws yog ib tug planar qauv. Txhua carbon atom yog sp hybridized.
YPropane yog dab tsi?
Propane yog ib qho yooj yim alkane uas muaj cov tshuaj formula C3H8 Nws yog roj tsis muaj xim ntawm chav tsev kub, thiab hauv nws cov ntshiab cov ntaub ntawv, cov pa roj no tsis muaj ntxhiab. Tsis tas li ntawd, nws cov molar loj yog 44.10 g / mol. Cov tshuaj no muaj kev siv ntau ua roj. LPG (liquefied petroleum gas) muaj liquefied propane gas.
Daim duab 02: Cov qauv tshuaj ntawm Propane
Txawm li cas los xij, muaj qee yam roj uas peb siv tau ua LP roj. Piv txwv li: Butane, propylene, butadiene, thiab lwm yam. Cov pa roj no ua los ntawm ob txheej txheem; natural gas processing thiab petroleum oil refining.
Qhov txawv ntawm Acetylene thiab Propane yog dab tsi?
Acetylene yog qhov yooj yim tshaj plaws alkyne uas muaj cov tshuaj formula C2H2 Cov molar mass ntawm no molecule yog 26.04 g / mol. Nws yog ib qho tsis txaus ntseeg vim tias nws muaj peb qhov sib txuas ntawm ob lub pa roj carbon atom nws muaj. Propane yog ib qho yooj yim alkane uas muaj cov tshuaj formula C3H8 Cov molar mass yog 44.01 g / mol. Nws yog ib qho saturated compound vim nws tsuas muaj ib daim ntawv cog lus ntawm atoms; tsis muaj ob daim ntawv cog lus lossis triple daim ntawv cog lus tam sim no.
Summary – Acetylene vs Propane
Acetylene thiab propane yog hydrocarbon compounds thiab yog gases ntawm chav tsev kub. Lawv yog cov tseem ceeb li roj. Qhov txawv ntawm acetylene thiab propane yog tias acetylene muaj triple daim ntawv cog lus ntawm ob lub pa roj carbon atoms whereas propane tsis muaj ob lossis triple bonds ntawm carbon atoms uas tsis yog ib daim ntawv cog lus.
