Qhov Tseem Ceeb Qhov txawv - 1-Butyne vs 2-Butyne
Txhua yam yooj yim aliphatic hydrocarbons tau muab faib ua peb hom raws li muaj cov pa roj carbon-carbon ib leeg lossis ntau daim ntawv cog lus: alkanes, alkenes, thiab alkynes. Alkanes yog saturated hydrocarbons thiab tsuas muaj ib qho carbon-carbon bonds. Cov mis loj ntawm alkane yog CnH2n+2. Qee cov alkanes muaj xws li methane, ethane, propane, thiab butane. Alkenes yog cov unsaturated unsaturated hydrocarbons nrog tsawg kawg yog ib tug carbon-carbon ob daim ntawv cog lus. Cov mis mos ntawm alkene yog CnH2n. Qhov yooj yim alkene yog ethylene. Butene, hexene, propene yog qee yam piv txwv rau alkenes. Alkynes yog unsaturated hydrocarbons nrog tsawg kawg yog ib qho carbon-carbon triple daim ntawv cog lus. Cov mis mos ntawm alkyne yog CnH2n-2. 1-butyne thiab 2-butyne yog ob qho yooj yim alkynes uas muaj ib qho carbon-carbon triple daim ntawv cog lus nyob rau hauv ntau qhov chaw. Ob leeg muaj tib cov qauv molecular ntawm C4H6, tab sis muaj qee qhov sib txawv. Qhov sib txawv tseem ceeb ntawm 1-butyne thiab 2-butyne yog nyob rau hauv 1-butyene, triple daim ntawv cog lus pom ntawm thawj thiab thib ob carbon, whereas nyob rau hauv 2-butyene, nws muaj nyob nruab nrab ntawm ob thiab thib peb carbon atoms. Vim qhov sib txawv no, ob yam khoom no muaj cov yam ntxwv sib txawv kiag li.
1-Butyne yog dab tsi?
1-butyne yog hu ua lub davhlau ya nyob twg alkyne vim muaj lub davhlau ya nyob twg triple daim ntawv cog lus ntawm thawj thiab thib ob carbon atoms ntawm cov saw hlau. Vim tias muaj cov ntawv cog lus no, 1-butyne tuaj yeem sib txawv ntawm 2-butyene los ntawm ob qhov kev sim loj. Hauv thawj qhov kev sim, ammoniacal cuprous chloride tov muab cov xim liab precipitate nrog 1-butyene, uas ua rau tooj liab 1-butynide. Hauv kev sim thib ob, cov tshuaj ammoniacal silver nitrate reacts nrog 1-butyne, uas ua rau nyiaj 1-butynide, uas yog dawb precipitate. Ob qho kev daws teeb meem no tsis cuam tshuam nrog 2-butyne.
Daim duab 01: 1-Butyne
1-butyne yog cov roj uas tsis muaj xim tsis muaj nplaim taws heev. Nws yog ntom dua li huab cua. Lub npe IUPAC ntawm 1-butyne yog but-1-yne.
2-Butyne yog dab tsi?
2-butyne yog ib qho tsis yog lub davhlau ya nyob twg alkyne, uas muaj nws daim ntawv cog lus triple nyob rau hauv nruab nrab ntawm cov saw hlau, txuas lub thib ob thiab thib peb carbon atoms. Tsis zoo li lub davhlau ya nyob twg alkynes, 2-butyne tsis hnov mob nrog ammoniacal cuprous chloride tov los yog ammoniacal silver nitrate tov los muab cov yam ntxwv precipitates. Lub davhlau ya nyob twg alkyl pawg ntawm 2-butyne muab electrons rau sp-hybridized carbon, yog li stabilizing alkyene thaum txo cov cua sov ntawm hydrogenation. Yog li, qhov kub ntawm hydrogenation tsawg dua hauv 2-butyne dua li hauv 1-butyne. 2-butyne yog cov kua uas tsis muaj xim thiab emits roj zoo li tsw. Nws muaj qhov ceev tsawg dua li dej thiab tsis soluble hauv dej. Lub npe IUPAC yog tab sis-2-yne.

Summary – 1-Butyne vs 2-Butyne
Ob leeg 1-butyne thiab 2-butyne yog cov hydrocarbons uas yog pawg ntawm alkynes. 1-butyne yog lub davhlau ya nyob twg alkyne uas muaj peb daim ntawv cog lus txuas C1 thiab C2. Nws yog xim tsis muaj roj. 2-butyne yog cov kua tsis muaj xim uas muaj nws daim ntawv cog lus triple txuas C2 thiab C3 atoms. Li no 2-butyne yog ib qho uas tsis yog-terminal alkyne. Vim qhov sib txawv ntawm 1-Butyne thiab 2-Butyne, ob lub hydrocarbons no muaj cov tshuaj lom neeg thiab lub cev sib txawv. Txawm li cas los xij, lawv cov qauv tshuaj yog tib yam, piv txwv li, C4H6
