Qhov sib txawv tseem ceeb ntawm cyclopropane propane thiab propene yog tias cyclopropane yog cyclic alkane, thiab propane yog non-cyclic alkane whereas propene yog alkene.
Cyclopropane, propane thiab propene yog cov organic tebchaw uas muaj peb carbon atoms ib molecule. Cov no yog hydrocarbon tebchaw tsuas muaj hydrogen thiab carbon atoms.
YCyclopropane yog dab tsi?
Cyclopropane yog cov organic compound uas muaj cov tshuaj formula (CH2)3 Nws yog ib qho cyclic compound thiab muaj peb carbon atoms txuas. rau ib leeg, tsim ib lub nplhaib qauv. Txhua carbon atom nyob rau hauv lub nplhaib no bears ob hydrogen atoms. Peb tuaj yeem txhais cov molecular symmetry ntawm no molecule li D3h symmetry. Ntxiv mus, muaj lub nplhaib siab vim yog lub nplhaib me me.
Cyclopropane compound tshwm sim raws li cov roj tsis muaj xim uas muaj ntxhiab tsw qab. Cov molar loj ntawm cyclopropane yog 42 g / mol. Lub melting point ntawm no compound yog -128 ° C thaum lub boiling point -33 ° C. Ntxiv mus, cyclopropane tuaj yeem ua tshuaj loog thaum nqus tau.

Muaj lub nplhaib strain nyob rau hauv qhov sib xyaw no tshwm sim vim qhov txo qis cov ces kaum, thiab tseem muaj qhov torsional strain vim eclipsed conformation. Yog li ntawd, cov tshuaj bonds nyob rau hauv cov qauv no yog comparatively tsis muaj zog tshaj cov coj alkane. Txoj kev ntxov tshaj plaws ntawm kev tsim cov cyclopropane yog los ntawm Wurtz coupling.
YPropane yog dab tsi?
Propane yog cov organic compound uas muaj cov tshuaj formula C3H8. Nws yog ib tug gaseous compound ntawm chav tsev kub thiab siab tej yam kev mob. Txawm li cas los xij, propane yog cov kua compressible, thiab nws yog cov kua xa tuaj thaum liquefied. Propane yog ib qho khoom siv los ntawm kev ua cov pa roj carbon monoxide uas cov roj av refining ua tiav. Ntxiv mus, propane muaj txiaj ntsig zoo li roj.
Daim duab 02: Ib Lub Tank Propane
Propane gas yog cov roj tsis muaj xim thiab tsis muaj ntxhiab tsw. Qhov kub ntawm qhov kub (txog 42 degrees Celsius) ntawm cov roj no tsawg heev, uas tso cai rau peb liquefy cov roj no. Nws kuj tseem tuaj yeem ua kom ruaj khov hauv qab nws qhov melting point (rho tawm 187.7 Celsius degrees), uas yog tus nqi qis heev.
Propane tuaj yeem raug combustion zoo ib yam li lwm cov tshuaj alkane. Yog tias muaj cov pa oxygen ntau dhau thaum lub sij hawm combustion, nws tsim dej vapor thiab carbon dioxide gas ua khoom. Yog tias cov pa oxygen tsis txaus rau kev ua kom tiav, ces nws tsim carbon monoxide thiab soot raws li cov khoom siv nrog rau cov dej vapor.
YPropene yog dab tsi?
Propene yog ib qho organic compound uas muaj cov tshuaj formula C3H6 Cov khoom hnyav ntawm cov tshuaj no yog kwv yees li 42.081 g / mol. Nyob rau hauv chav tsev kub thiab siab tej yam kev mob, qhov no yog ib tug colorless roj. Tsis tas li ntawd, cov roj no muaj cov ntxhiab tsw zoo li roj av. Propene muaj cov Carbon thiab Hydrogen atoms uas sib koom ua ke ntawm ib daim ntawv cog lus, thiab muaj ob daim ntawv cog lus ntawm ob lub atoms. Yog li ntawd, propene yog ib qho tsis muaj qhov sib xyaw ua ke.
Daim duab 03: Cov qauv tshuaj ntawm Propene
Peb tuaj yeem faib cov propene ua alkene uas muaj cov ntawv cog lus sigma thiab daim ntawv cog lus pi. Hauv lwm lo lus, qhov sib xyaw no muaj ob daim ntawv cog lus ntawm ob lub atoms carbon. Propene muaj trigonal planar tshuaj geometry nyob ib ncig ntawm ob daim ntawv cog lus. Vim yog qhov tsis txaus ntawm qhov sib xyaw no, propene tseem ceeb heev hauv kev tsim cov khoom sib xyaw polymer. Qhov ob daim ntawv cog lus nyob rau hauv cov molecule no yuav undergo polymerization ntxiv los ntawm kev qhib ob daim ntawv cog lus. Cov polymer ua los ntawm propene yog poly (propene) (ib lub npe yog polypropylene).
Qhov txawv ntawm Cyclopropane Propane thiab Propene yog dab tsi?
Cyclopropane, propane thiab propene yog cov organic tebchaw uas tsuas muaj cov pa roj carbon thiab hydrogen atoms. Qhov sib txawv tseem ceeb ntawm cyclopropane propane thiab propene yog tias cyclopropane yog cyclic alkane thiab propane yog non-cyclic alkane, whereas propene yog alkene.
Cov hauv qab no infographic tabulates ntau qhov sib txawv ntawm cyclopropane propane thiab propene.
Summary – Cyclopropane Propane vs Propene
Cyclopropane, propane thiab propene yog cov organic tebchaw uas tsuas muaj cov pa roj carbon thiab hydrogen atoms. Qhov sib txawv tseem ceeb ntawm cyclopropane propane thiab propene yog tias cyclopropane yog cyclic alkane thiab propane yog non-cyclic alkane, whereas propene yog alkene.
