Qhov txawv ntawm ethane thiab ethanol yog ethane yog alkane whereas ethanol yog cawv.
Ob leeg ethane thiab ethanol yog cov organic tebchaw. Txawm li cas los xij, ob qho tib si no txawv ntawm ib leeg hauv ntau txoj hauv kev. Raws li, ethane yog ib qho alkane, uas txhais tau hais tias nws tsis muaj ob lossis triple bonds ntawm cov pa roj carbon atoms; tsuas yog ib daim ntawv cog lus xwb. Ethanol yog cawv, uas txhais tau hais tias nws muaj ib pawg hydroxyl (-OH) raws li nws pawg ua haujlwm.
Ethane yog dab tsi?
Ethane yog cov organic compound uas muaj cov tshuaj formula C2H6 Nws yog alkane thiab yooj yim aliphatic hydrocarbon molecule. Ethane yog hydrocarbon vim nws tsuas muaj carbon thiab hydrogen atoms. Ethane yog alkane vim nws tsis muaj ntau daim ntawv cog lus ntawm carbon atoms. Tsis tas li ntawd, carbon atoms ntawm ethane muaj ntau tshaj plaws ntawm hydrogen atoms uas cov carbon atoms muaj peev xwm muaj, ua rau nws saturated alkane.
Daim duab 01: Cov Qauv Tshuaj ntawm Ethane
Ethane muaj nyob hauv cov pa tsis muaj xim thiab tsw ntxhiab ntawm qhov ntsuas kub thiab siab. Qhov hnyav molecular ntawm no compound yog 30 g mol-1 Ntxiv mus, txhua cov pa roj carbon atom hauv cov molecule no muaj tetrahedral geometry. Li no, H-C-H daim ntawv cog lus yog 109o Cov pa roj carbon atoms hauv ethane yog sp3 hybridized atoms. Nyob ntawd, ib qho sp3 hybridized orbital los ntawm txhua cov pa roj carbon atom sib tshooj ua kom cov pa roj carbon-carbon sigma daim ntawv cog lus. Cov kev sib raug zoo ntawm carbon thiab hydrogen kuj yog ib daim ntawv cog lus, tab sis nws yog tsim los ntawm overlapping ib sp3 hybridized orbital ntawm cov pa roj carbon nrog tib lub orbital ntawm hydrogen atom.
Vim tias tib sigma daim ntawv cog lus ntawm carbon atoms, daim ntawv cog lus sib hloov hauv ethane yog ua tau, thiab nws tsis tas yuav muaj lub zog loj. Ethane yog ib feem ntawm cov pa roj carbon monoxide, yog li peb tuaj yeem cais nws los ntawm cov pa roj carbon monoxide loj. Tsis tas li ntawd, peb tuaj yeem tau txais cov khoom siv roj av no los ntawm cov khoom lag luam hauv roj av refining.
Ethanol yog dab tsi?
Ethanol yog cawv yooj yim nrog cov mis molecular ntawm C2H5OH. Nws yog cov kua ntshiab, tsis muaj xim uas muaj ntxhiab tsw. Tsis tas li ntawd, nws muaj cov kua ua kua ntawm qhov ntsuas kub thiab siab. Lub melting point ntawm cov cawv no yog -114.1 o C, thiab lub boiling point yog 78.5 o C. Tsis tas li ntawd, ethanol yog polar vim qhov sib txawv ntawm electronegativity ntawm oxygen thiab hydrogen hauv pawg -OH. Tsis tas li vim yog -OH pawg, nws muaj peev xwm tsim cov ntawv cog lus hydrogen.
Daim duab 02: Cov qauv tshuaj ntawm Ethanol
Ethanol muaj txiaj ntsig zoo li dej haus. Raws li ethanol feem pua, muaj ntau hom dej haus xws li cawv, npias, whiskey, brandy, arrack, thiab lwm yam. Tsis tas li ntawd, peb tuaj yeem yooj yim tau cov cawv no los ntawm cov txheej txheem qab zib fermentation siv zymase enzyme. Cov enzyme no tshwm sim hauv cov poov xab, yog li hauv kev ua pa anaerobic, poov xab tuaj yeem tsim ethanol. Ethanol yog tshuaj lom rau lub cev, thiab nws hloov mus rau hauv acetaldehyde hauv daim siab, uas yog tshuaj lom. Lwm yam tshaj li dej haus nws yog ib qho tseem ceeb raws li ib tug antiseptic los ntxuav qhov chaw ntawm cov kab mob. Feem ntau, peb tuaj yeem siv nws ua roj thiab roj ntxiv hauv tsheb. Ethanol yog miscible nrog dej, thiab nws kuj yog ib qho hnyav hnyav.
Qhov txawv ntawm Ethane thiab Ethanol yog dab tsi?
Ethane yog ib qho organic compound uas muaj cov tshuaj formula C2H6 whereas ethanol yog cawv yooj yim nrog cov mis molecular ntawm C 2H5OH. Qhov sib txawv tseem ceeb ntawm ethane thiab ethanol yog tias ethane yog alkane thaum ethanol yog cawv. Txawm li cas los xij, ob qho tib si yog cov organic tebchaw. Thaum xav txog cov tshuaj muaj pes tsawg leeg ntawm ob lub tebchaw, ethane muaj carbon thiab hydrogen atoms thaum ethanol muaj carbon, hydrogen thiab oxygen atoms. Tsis tas li ntawd, qhov kub thiab txias ntawm ethanol yog qhov sib piv siab dua li ntawm ethane vim tias ethanol tuaj yeem tsim cov ntawv cog lus muaj zog xws li hydrogen bonds ntawm cov molecules uas ethane tsis tuaj yeem.
Raws li lwm qhov sib txawv tseem ceeb ntawm ethane thiab ethanol, ethane muaj nyob hauv cov pa roj carbon monoxide whereas ethanol muaj nyob hauv cov kua sib xyaw ntawm tus qauv kub thiab siab. Cov nram qab no infographic ntawm qhov sib txawv ntawm ethane thiab ethanol qhia ntau qhov sib txawv ntawm ob qho tib si.
Summary – Ethane vs Ethanol
Ethane thiab cawv yog cov organic tebchaw tseem ceeb uas tau siv hauv kev lag luam nrog rau ntau qhov chaw xws li tshuaj, tshuaj synthesis, thiab lwm yam. Qhov txawv ntawm ethane thiab ethanol yog ethane yog alkane whereas ethanol yog cawv..
