Butan-1-ol, tseem hu ua n-butanol yog thawj cawv nrog cov tshuaj formula C₄H₉OH thiab cov qauv linear. Isomers ntawm butan-1-ol yog isobutanol, butan-2-ol thiab tert-butanol. Lub sij hawm tsis hloov pauv butanol feem ntau yog hais txog cov saw ncaj isomer.
Koj sau li cas butanol?
Butanol (tseem hu ua butyl cawv) yog plaub-carbon cawv nrog cov qauv ntawm C4H9 OH, uas tshwm sim nyob rau hauv tsib isomeric qauv (plaub lub qauv isomers), los ntawm ib tug ncaj-chain thawj cawv rau ib tug branched-chain tertiary cawv; tag nrho yog ib pawg butyl lossis isobutyl txuas rau pawg hydroxyl (qee zaum sawv cev raws li …
butanol zoo li cas?
Sec-butyl cawv tshwm li cov kua ntshiab tsis muaj xim nrog cov ntxhiab tsw ntxhiab. Teeb nyem hauv qab 0 ° F. Tsawg dua li dej.
YPuas yog 2-butanol yog cawv tertiary?
2-methylbutan-2-ol yog tertiary cawv uas yog propan-1-ol uas ob qho tib si ntawm hydrogens ntawm txoj haujlwm 1 tau hloov los ntawm pawg methyl.
YPuas yog butanol acidic lossis yooj yim?
Yog li ntawd, nyob rau hauv cov roj-theem, t-butanol yog feem ntau acidic cawv, acidic ntau dua isopropanol, ua raws li ethanol thiab methanol. Nyob rau hauv cov roj theem, dej yog acidic tsawg dua methanol, uas yog raws li qhov sib txawv ntawm polarizibility ntawm ib tug proton thiab ib pawg methyl.
