Isopropyl vs Ethanol
Organic molecules yog cov molecules uas muaj carbons. Organic molecules yog cov molecule ntau tshaj plaws nyob rau hauv lub ntiaj teb no. Cov organic molecules tseem ceeb hauv cov khoom muaj sia muaj xws li carbohydrates, proteins, lipids, thiab nucleic acids. Nucleic acids zoo li DNA muaj cov ntaub ntawv keeb kwm ntawm cov kab mob. Carbon tebchaw zoo li cov proteins ua cov yam ntxwv ntawm peb lub cev, thiab lawv tsim cov enzymes uas catalyze tag nrho cov metabolic zog. Muaj pov thawj los ua pov thawj tias carbonic molecules zoo li methane muaj nyob hauv huab cua txawm ntau txhiab xyoo dhau los. Tsis yog peb tsuas yog tsim los ntawm cov organic molecules, tab sis muaj ntau hom organic molecules nyob ib ncig ntawm peb ib yam nkaus uas peb siv txhua hnub rau ntau lub hom phiaj.
Cov khaub ncaws peb hnav yog tsim los ntawm ntuj lossis hluavtaws organic molecules. Ntau cov ntaub ntawv hauv peb lub tsev kuj yog cov organic. Roj av, uas muab lub zog rau tsheb thiab lwm yam tshuab, yog cov organic. Feem ntau ntawm cov tshuaj peb noj, tshuaj tua kab, thiab tshuaj tua kab yog tsim los ntawm cov organic molecules. Yog li, cov organic molecules yog txuam nrog ze li ntawm txhua yam ntawm peb lub neej. Yog li ntawd, ib qho kev kawm cais raws li cov organic chemistry tau hloov zuj zus mus kawm txog cov tebchaw no. Organic molecules yog dav categorized li aliphatic thiab aromatic compounds. Lawv tuaj yeem muab faib ua cov ceg ntoo lossis tsis muaj ceg. Lwm categorization yog raws li hom kev ua haujlwm pab pawg uas lawv muaj. Nyob rau hauv no categorization, organic molecules muab faib rau alkanes, alkenes, alkyne, cawv, ether, amine, aldehyde, ketone, carboxylic acid, ester, amide thiab haloalkanes.
Isopropyl
Propyl pawg yog ib pawg hydrocarbon nrog peb carbon atoms. Nws muaj xya hydrogen atoms txuas nrog carbon atoms, thiab tag nrho cov pab pawg neeg yog ib tug hloov ntawm ib tug organic molecule. Propyl muaj cov qauv ntawm –CH2 CH2 CH3 Isopropyl muaj tib cov mis, tab sis cov kev sib txuas sib txawv me ntsis. Yog li nws zoo li kev cai lij choj isomeric daim ntawv ntawm pawg propyl. Isopropyl muaj cov qauv hauv qab no.
Hauv IUPAC nomenclature, nws yog lub npe hu ua propan-2-yl. Isopropyl pawg tsis ruaj khov nyob ib leeg. Nws txuas nrog lwm qhov thiab ua kom tiav thiab ruaj khov molecule. Piv txwv li, isopropyl cawv tuaj yeem noj.
Ethanol Nyob
Ethanol yog ib qho cawv yooj yim nrog cov mis molecular ntawm C2H5OH. Nws yog cov kua ntshiab, tsis muaj xim, nrog cov yam ntxwv tsw. Tsis tas li ntawd, ethanol yog cov kua ua kua. Melting point ntawm ethanol yog -114.1 o C, thiab kub taw tes yog 78.5 o C. Ethanol yog polar vim qhov sib txawv ntawm electronegativity ntawm oxygen thiab hydrogen hauv pawg -OH. Tsis tas li ntawd, vim yog pawg -OH, nws muaj peev xwm tsim cov ntawv cog lus hydrogen.
Ethanol yog siv los ua dej haus. Raws li ethanol feem pua, muaj ntau hom dej haus xws li cawv, npias, whiskey, brandy, arrack, thiab lwm yam Ethanol tau yooj yim tau 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 acetaldehyde hauv daim siab, uas yog tshuaj lom. Lwm yam tshaj li dej haus ethanol tuaj yeem siv los ua cov tshuaj tua kab mob los ntxuav cov kab mob ntawm cov kab mob, thiab nws yog siv los ua roj thiab roj ntxiv hauv tsheb. Ethanol yog miscible nrog dej, thiab nws kuj yog ib qho hnyav hnyav.
