Cov kuab tshuaj sib cais fluorene thiab 9 - tshuaj fluorenone raws li lawv qhov sib txawv ntawm cov qauv thiab polarity . Nyob rau hauv txoj cai, cov tshuaj compound uas ntws los ntawm kem ntawm ib tug ceev ceev yog ntau tsis- polar ; yog li ntawd, hauv qhov no fluorene yog ntau tsis- polar 9 - tshuaj fluorenone.

Ib yam li ntawd, tib neeg nug, qhov twg ntau dua polar fluorene lossis fluorenone?

Fluorenone yog ntau polar tshaj fluorene vim C=O. daim ntawv cog lus. Flask peb tsuas yog yuav tsum muaj Fluorenone tab sis qhov no qhia txog kev sib kis ntawm lwm qhov sib xyaw. Rau ib tug sib tov ntawm fluorene , tshuaj fluorenone thiab -fluorenol raug tshuaj xyuas los ntawm TLC thiab muab cov txiaj ntsig Rf hauv qab no: 0.3, 0.5, 0.8.

Tsis tas li ntawd, puas yog 9 Fluorenone ntau dua polar dua ferrocene? Liquid Column Chromatography thiab ThinLayer Chromatography ob leeg tau siv los cais tawm cov ntshiab ferrocene , 9 Fluorenone , thiab Acetyl Ferrocene . Qhov no ua rau kev nkag siab nrog cov txiaj ntsig, txij li Ferrocene yog nonpolar, 9 fluorenone ua yog me ntsis polar nrog nws pawg carbonyl, thiab acetylferrocene yog polar nrog nws pawg acetyl.

Ib yam li ntawd, koj tuaj yeem nug, vim li cas 9 Fluorenone polar?

Zuag qhia tag nrho, tshuaj fluorenone yog a polar Kev sib xyaw ua ke, feem ntau yog vim muaj cov ketone. Txij li cov pa oxygen ntau dua electronegative dua carbon, muaj kev sib koom tsis sib xws ntawm cov electrons nyob rau hauv daim ntawv ntawm ob daim ntawv cog lus, ua rau nws. polar.

Puas yog fluorene lossis 9 Fluorenone txav nrawm dua hauv kab?

Vim lub fluorene thiab hexanes yog nonpolar, yog li lawv txav sai sai los ntawm polar alumina gel. Vim lub 9 - tshuaj fluorenone yog polar, nws maj mam txav hauv qab kem.
