Qhov sib txawv tseem ceeb ntawm tert butyl thiab isobutyl yog tias pawg tert butyl muaj cov saw hlau ob leeg thaum lub isobutyl muaj ib leeg ceg ntoo.
Ob lo lus tert butyl thiab isobutyl hais txog ob pawg ua haujlwm sib txawv hauv cov tshuaj lom neeg. Txawm li cas los xij, ob pawg no muaj tib tus lej ntawm carbon atoms thiab hydrogen atoms tab sis muaj qhov sib txawv ntawm qhov sib txawv ntawm cov atoms. Cov tshuaj formula ntawm ob qho tib si yog −C4H9 Ntxiv mus, cov pab pawg no yuav muaj nyob ua radicals lossis pawg ua haujlwm.
Tert Butyl yog dab tsi?
Tert butyl yog plaub cov pa roj carbon alkyl radical lossis pab pawg ua haujlwm uas lub chaw nruab nrab carbon txuas nrog peb pawg methyl. Yog li ntawd, cov pab pawg no muaj ib tug ob leeg branched alkane qauv. Nyob ntawd, lub hauv paus carbon atom uas txuas nrog peb pawg methyl muaj qhov chaw tsis muaj qhov chaw uas muaj qhov sib txawv ntawm cov molecule tuaj yeem txuas rau.
Daim duab 01: Tert Butyl Acetate
Vim cov pab pawg ua haujlwm muaj peb pawg methyl, peb hu nws ua tertiary-butyl, tert-butyl lossis t-butyl. Lub npe systematic rau pawg no yog "1, 1-dimethyl ethyl", thiab cov tshuaj formula yog (CH3)3C-.
Ex: tert-butyl acetate muaj ib pawg tert-butyl ua haujlwm txuas nrog pawg acetate.
Isobutyl yog dab tsi?
Isobutyl yog plaub cov pa roj carbon alkyl radical lossis pab pawg ua haujlwm nyob rau hauv uas muaj peb-tus tswvcuab cov saw txuas nrog ib pawg methyl ntawm nws cov pa roj carbon thib ob. Yog li ntawd, pawg ua haujlwm no muaj ib ceg methyl. Peb cov pa roj carbon monoxide muaj ib pawg methyl ntawm cov pa roj carbon thib ob thaum cov pa roj carbon monoxide thib peb muaj qhov chaw tsis muaj qhov uas cov moiety ntawm ib lub molecule yuav txuas nrog.
Daim duab 02: Isobutyl Acetate
Cov tshuaj formula rau pawg no yog (CH3)2CH-CH2 -, thiab lub npe systematic yog "2-methyl propyl".
Ex: isobutyl acetate muaj ib pawg isobutyl ua haujlwm txuas nrog pawg acetate.
Qhov txawv ntawm Tert Butyl thiab Isobutyl yog dab tsi?
Tert butyl yog plaub cov pa roj carbon alkyl radical lossis pab pawg ua haujlwm nyob rau hauv uas lub chaw carbon txuas nrog peb pawg methyl whereas isobutyl yog plaub cov pa roj carbon alkyl radical lossis pawg ua haujlwm uas muaj peb-tus tswvcuab carbon saw txuas nrog ib pawg methyl. ntawm nws thib ob carbon atom. Yog li, qhov no yog qhov sib txawv ntawm tert butyl thiab isobutyl. Ntxiv mus, qhov sib txawv saum toj no ua rau muaj qhov sib txawv tseem ceeb ntawm tert butyl thiab isobutyl. Ntawd yog, pawg tert butyl muaj cov qauv ob leeg thaum cov isobutyl pawg muaj ib qho qauv ntawm ib ceg. Tsis tas li ntawd, lub npe systematic ntawm tert butyl yog 1, 1-dimethyl ethyl thaum lub isobutyl yog 2-methyl propyl.
Cov hauv qab no infographic tabulates qhov sib txawv ntawm tert butyl thiab isobutyl ua ib sab ntawm kev sib piv.
Summary – Tert Butyl vs Isobutyl
Lo lus butyl thiab isobutyl yog pawg ua haujlwm uas yog isomers ntawm ib leeg. Yog li ntawd, lawv muaj tib lub atomic muaj pes tsawg leeg, tab sis txawv atomic kev npaj. Qhov sib txawv tseem ceeb ntawm tert butyl thiab isobutyl yog cov pab pawg tert butyl muaj cov saw hlau ob leeg thaum isobutyl muaj cov saw hlau ib leeg.
