Nonpolar cov kuab tshuaj muaj xws li alkanes (pentane, hexane, thiab heptane) thiab aromatics (benzene, toluene, thiab xylene). Lwm cov kuab tshuaj nonpolar muaj xws li acetic acid, chloroform, diethyl ether, ethyl acetate, methylene chloride, thiab pyridine.
Dab tsi yog cov kuab tshuaj polar thiab piv txwv?
Cov kuab tshuaj tsis muaj polar yog cov khoom sib xyaw uas muaj qhov tsis zoo ntawm cov dielecrtic thiab tsis sib xyaw nrog dej. Piv txwv suav nrog benzene (C 6 H 6), carbon tetrachloride (CCl4), thiab diethyl ether (CH3CH2OCH2CH3) … Tag nrho cov kuab tshuaj no yog kua ntshiab, tsis muaj xim. Cov hydrogen atoms ntawm cov kuab tshuaj protic yog qhia hauv liab.
Qhov hnyav hnyav twg yog nonpolar?
Non-Polar Solvent
- Hydrogen.
- Polar Solvent.
- Hexane.
- Toluene.
- Ligand.
- Surfactant.
- Benzene.
- Solubility.
polar solvent yog dab tsi?
Polar solvents muaj loj dipole moments (aka "ib feem nqi"); lawv muaj kev sib txuas ntawm cov atoms nrog cov electronegativities sib txawv, xws li oxygen thiab hydrogen. Cov kuab tshuaj tsis muaj polar muaj cov ntawv cog lus ntawm cov atoms nrog cov electronegativities zoo sib xws, xws li carbon thiab hydrogen (xav tias hydrocarbons, xws li roj av).
Puas yog dej tsis yog polar solvent?
Polar/ionic solvents dissolve polar/ionic solutes thiab non-polar solvents dissolve non-polar solutes. Piv txwv li, dej yog cov kuab tshuaj polar thiab nws yuav yaj cov ntsev thiab lwm cov polar molecules, tab sis tsis yog polar molecules zoo li roj. Petrol yog cov kuab tshuaj uas tsis yog-polar thiab yuav yaj cov roj, tab sis yuav tsis tov nrog dej.
