Qhov txawv ntawm 1 2 ntxiv thiab 1 4 ntxiv yog tias hauv 1 2 ntxiv, cov pab pawg ua haujlwm txuas rau 1st thiab 2 nd carbon atoms ntawm qee cov saw hlau, whereas hauv 1 4 ntxiv txheej txheem, cov pab pawg ua haujlwm txuas rau 1st thiab 4th carbon atoms ntawm cov saw hlau.
1 2 ntxiv lossis 1, 2-ntxiv thiab 1 4 ntxiv lossis 1, 4-ntxiv yog ob qhov tseem ceeb ntxiv cov txheej txheem tshuaj tiv thaiv uas tshwm sim hauv cov organic tebchaw. Cov no tseem ceeb heev kom tau txais cov khoom lag luam organic uas xav tau.
1 2 Ntxiv yog dab tsi?
1 2 ntxiv lossis 1, 2-ntxiv yog ib hom tshuaj lom neeg cov tshuaj tiv thaiv uas koom nrog kev sib ntxiv ntawm pawg ua haujlwm rau 1st thiab 2ndcarbon atoms ntawm cov saw hlau. Hauv lwm lo lus, cov pab pawg ua haujlwm hauv cov khoom ntawm cov tshuaj tiv thaiv no txuas nrog cov pa roj carbon atoms uas nyob ib sab. Ntxiv mus, 1, 2-ntxiv cov tshuaj tiv thaiv muaj lub zog ua kom me me piv rau 1 4 ntxiv cov tshuaj tiv thaiv.
Daim duab 1: Kev Ntxiv ntawm HCl rau Cyclic Structure Muab 1, 2-Cov Khoom Ntxiv
Nyob rau hauv daim duab saum toj no, cov qauv cyclic muaj ob daim ntawv cog lus ntawm ob lub atoms. H thiab Cl atoms ntawm hydrochloric acid compound (HCl) tshem tawm lawv daim ntawv cog lus thiab txuas mus rau cov qauv cyclic los ntawm ob daim ntawv cog lus tawg. Yog li ntawd, ob pawg ua haujlwm, H thiab Cl, nyob ntawm cov pa roj carbon atoms uas nyob ib sab.
1 4 Ntxiv yog dab tsi?
1 4 ntxiv lossis 1, 4-ntxiv yog ib hom tshuaj lom neeg cov tshuaj tiv thaiv uas koom nrog kev sib ntxiv ntawm pawg ua haujlwm rau 1st thiab 2ndcarbon atoms ntawm cov saw hlau. Qhov no txhais tau hais tias cov pab pawg ua haujlwm hauv cov khoom ntawm 1 4 ntxiv cov tshuaj tiv thaiv yog txuas nrog cov pa roj carbon atoms uas tsis nyob ib sab. Ntxiv mus, 1, 4-ntxiv cov tshuaj tiv thaiv muaj zog ua kom ntau dua piv rau 1 2 ntxiv cov tshuaj tiv thaiv.
Daim duab 02: 1, 3-Butadiene Polymerization Reaction Qhia Ob 1, 2-Ntxiv thiab 1, 4-Ntxiv Cov Lus Teb
Cov piv txwv saum toj no hauv daim duab qhia pom qhov sib ntxiv ntawm monomers los ua ib lub polymer. Cov monomers txuas rau ib leeg los ntawm 1st thiab 4th carbon atoms ntawm txhua txoj saw (tshwj tsis yog cov monomers qhov twg 1, 2-ntxiv ntxiv muaj tshwm sim).
Qhov txawv ntawm 1 2 Ntxiv thiab 1 4 Ntxiv yog dab tsi?
1 2 ntxiv lossis 1, 2-ntxiv thiab 1 4 ntxiv lossis 1, 4-ntxiv yog ob qhov tseem ceeb ntxiv cov txheej txheem tshuaj tiv thaiv uas tshwm sim hauv cov organic tebchaw. Qhov sib txawv tseem ceeb ntawm 1 2 ntxiv thiab 1 4 ntxiv yog tias hauv 1 2 ntxiv, cov pab pawg ua haujlwm txuas rau 1st thiab 2nd carbon atoms ntawm ib tug tej yam carbon saw, whereas nyob rau hauv 1 4 ntxiv txheej txheem, cov functional pawg tau txuas mus rau lub 1st thiab 4th carbon atoms ntawm lub carbon saw hlau. Ntxiv mus, 1 4 ntxiv cov tshuaj tiv thaiv muaj zog ua kom muaj zog dua li 1 2 ntxiv cov tshuaj tiv thaiv. Tsis tas li ntawd, hauv 1 2 ntxiv, cov pab pawg ua haujlwm tau txuas nrog cov pa roj carbon atoms uas nyob ib sab, hos hauv 1 4 ntxiv, cov pab pawg ua haujlwm tau txuas nrog cov pa roj carbon atoms uas tsis nyob ib sab.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm 1 2 ntxiv thiab 1 4 ntxiv rau hauv daim ntawv tabular hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – 1 2 Ntxiv vs 1 4 Ntxiv
1 2 ntxiv thiab 1 4 ntxiv yog qhov tseem ceeb heev kom tau txais cov khoom lag luam organic uas xav tau. Qhov sib txawv tseem ceeb ntawm 1 2 ntxiv thiab 1 4 ntxiv yog tias hauv 1 2 ntxiv, cov pab pawg ua haujlwm txuas rau 1st thiab 2nd carbon atoms ntawm ib co carbon atoms, whereas nyob rau hauv 1 4 ntxiv txheej txheem, cov functional pawg tau txuas mus rau lub 1st thiab 4th carbon atoms ntawm cov pa roj carbon saw. Ntxiv mus, 1 4 ntxiv cov tshuaj tiv thaiv muaj zog ua kom muaj zog dua li 1 2 ntxiv cov tshuaj tiv thaiv.
