Qhov sib txawv tseem ceeb ntawm isobutyl thiab sec-butyl yog cov isobutyl pawg qhia nws cov qauv ceg ntawm cov pa roj carbon thib ob ntawm cov saw hlau, thaum pawg sec-butyl qhia nws cov qauv ceg ntawm thawj carbon atom ntawm cov saw hlau..
Lub sij hawm butyl pawg yog hais txog plaub-carbon alkyl radical lossis pab pawg hloov pauv uas muaj cov tshuaj formula -C4H9. Cov pab pawg ua haujlwm no feem ntau tsim los ntawm ib qho ntawm butane ob qho isomers: n-butane lossis isobutane. Cov pab pawg ua haujlwm uas tau txais los ntawm n-butane yog pawg n-butyl uas muaj cov saw hlau aliphatic yooj yim ntawm plaub carbon atoms. Txawm li cas los xij, yog tias muaj cov saw hlau ntawm peb cov pa roj carbon atom thiab ib ceg ntawm pawg methyl (ib qho methyl hloov) uas tshwm sim ntawm thawj cov pa roj carbon atom (cov pa roj carbon atom uas nyob ze rau pawg R lossis qhov chaw seem ntawm pawg ua haujlwm.), tom qab ntawd pab pawg ua haujlwm no muaj npe hu ua pawg sec-butyl lossis pawg butyl pawg thib ob. Cov tshuaj formula rau hom butyl pawg no yog CH3-CH2CH(CH3)-.
Isobutyl yog dab tsi?
Isobutyl ua haujlwm pab pawg yog plaub-carbon alkyl radical lossis pab pawg ua haujlwm uas muaj peb-tus tswvcuab cov saw hlau txuas rau ib pawg methyl ntawm nws cov pa roj carbon thib ob. Yog li ntawd, pawg ua haujlwm no muaj ib ceg methyl. Cov saw hlau muaj peb-tus tswv cuab muaj cov methyl pawg ntawm cov pa roj carbon thib ob, thaum cov pa roj carbon thib peb muaj qhov tsis muaj qhov chaw uas muaj qhov sib txawv ntawm cov molecule tuaj yeem txuas nrog.
Daim duab 01: Cov Qauv Tshuaj ntawm Isobutyl Functional Group
Cov tshuaj formula rau pawg no yog CH3-CH(CH3)-CH2-, thiab lub npe hu ua "2-methyl propyl". Piv txwv li: isobutyl acetate muaj ib pawg isobutyl ua haujlwm nrog rau pawg acetate. Ntxiv mus, isobutyl yog ib hom ntawm pawg sec-butyl functional.
Sec-butyl yog dab tsi?
Sec-butyl pawg yog ib qho derivative ntawm butyl functional pab pawg uas muaj ib tug branched qauv. Feem ntau, ib pawg sec-butyl muaj peb-carbon atom saw nrog methyl hloov ntawm thawj cov pa roj carbon atom lossis cov pa roj carbon atom uas nyob ib sab mus rau qhov chaw seem ntawm pawg ua haujlwm.
Daim duab 02: Sec-butyl Functional Group Chemical Structure
Ntxiv rau, thaum cov khoom hloov pauv yog thawj carbon atom, ces nws muaj cov tshuaj formula CH3-CH2CH(CH3)- thiab cov tshuaj npe ntawm pawg yog 1-methyl propyl.
Qhov txawv ntawm Isobutyl thiab Sec-butyl yog dab tsi?
Butyl ua haujlwm pab pawg yog plaub-tus tswvcuab saw qauv. Muaj ntau hom kev ua haujlwm ntawm butyl pawg nyob ntawm cov qauv tshuaj. Isobutyl thiab sec-butyl yog ob hom ntawv. Qhov sib txawv tseem ceeb ntawm isobutyl thiab sec-butyl yog pab pawg isobutyl qhia nws cov qauv ceg ntawm cov pa roj carbon thib ob ntawm cov saw hlau, thaum pawg sec-butyl qhia nws cov qauv ceg ntawm thawj carbon atom ntawm cov saw hlau. Isobutyl cov ntaub ntawv isobutyl cov tebchaw xws li isobutyl cawv thaum sec-butyl tsim cov khoom sib txuas-carbon xws li cawv thib ob. Qhov no yog lwm qhov sib txawv ntawm isobutyl thiab sec-butyl.
Cov infographic hauv qab no nthuav tawm qhov sib txawv ntawm isobutyl thiab sec-butyl hauv daim ntawv tabular.
Summary – Isobutyl vs Sec-butyl
Butyl ua haujlwm pab pawg yog plaub-tus tswvcuab saw qauv. Isobutyl thiab sec-butyl yog ob hom ntawm butyl functional pawg. Qhov sib txawv tseem ceeb ntawm isobutyl thiab sec-butyl yog pab pawg isobutyl qhia nws cov qauv ceg ntawm cov pa roj carbon thib ob ntawm cov saw hlau, thaum pawg sec-butyl qhia nws cov qauv ceg ntawm thawj carbon atom ntawm cov saw hlau.
