Benzophenone , uas feem ntau tsis muaj polar, tab sis muaj ib pawg polar carbonyl, tau pom tias yog ib feem soluble hauv methyl cawv thiab hexane tab sis insoluble hauv dej. Malonic acid, ib tug polar molecule uas tseem muaj peev xwm ionize, tau pom tias yuav soluble hauv dej thiab methyl cawv tab sis insoluble hauv hexane.

Yog li ntawd, benzophenone puas yog kua?

Benzophenone yog cov organic compound nrog cov mis (C6H5)2CO, feem ntau abbreviated Ph2CO. Nws yog cov khoom dawb uas yog soluble hauv cov kuab tshuaj organic.

Benzophenone.

Qhov thib ob, vim li cas benzophenone soluble hauv methyl cawv? Methyl cawv muaj nruab nrab polarity tab sis benzophenone yog soluble hauv nws vim, benzophenone muaj ib tug polar carbonyl pawg uas muaj peev xwm mus hydrogen daim ntawv cog lus nrog methyl cawv . Hauv hexane, benzophenone yog ib nrab soluble . Hexane kuj yog nonpolar, yog li biphenyl muaj peev xwm yaj.

Hais txog qhov no, yog vim li cas benzophenone nyob rau hauv chav tsev kub?

Cov xwm txheej raug sim. 2) benzophenone yog ib qho tshuaj tsw qab, nrog ntau dua MW tshaj cyclohexanone. Nws muaj ntau txoj hauv kev los cuam tshuam hauv kev sib cuam tshuam hauv kev sib txawv (ntawm cov rog dispersion) dua li cyclohexanone. qhov no feem ntau yuav yog vim li cas nws yog khoom ntawm chav tsev temp.

Puas yog biphenyl soluble hauv methyl cawv?

Biphenyl yog ib nrab soluble hauv methanol uas yog intermediate polar whilst biphenyl yog nonpolar, cia nws mus yaj me ntsis. Txawm li cas los xij, biphenyl yog polar tsawg dua benzophenone. Txij li thaum methyl cawv yog me ntsis polar, qhov polar benzophenone ntau dua soluble nyob rau hauv methyl cawv tshaj biphenyl.
