Since ligroin is a nonpolar solvent (composed of 6-carbon alkanes), nonpolar sample molecules will easily dissolve in the solvent and not adsorb to the polar silica gel. Likewise, polar sample molecules will strongly adsorb to the stationary silica gel.What...
Acetone is a good solvent because it has both polar and non-polar elements. Its methyl groups are non-polar, which means that it can act as a solvent...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your...
What is the molecular formula of acetone? What is solubility in physical chemistry? What is a pure substance in chemistry? The greatest solvent in the world is What is a compound in chemistry? What is dissolution in chemistry? What property of water allows water to work as a universal solven...

Octane is a nonpolar hydrocarbon found in gasoline while water is a highly polar hydrogen-bonding solvent. Octane can't from hydrogen bonds, so there is no good way for the molecules of these two substances to intract strongly with each other. There ar
Is benzaldehyde polar or nonpolar? What is the most hydrophobic molecule? Do you know whether 1-propanol is a polar or non-polar molecule? What is the shape of a water molecule? Is HCl polar? How to figure out polarity of a molecule a) Are there polar bonds in Acetone? (Show EN for...
The formation of relatively strongly hydrogen-bonded complexes between HOOOH and organic oxygen bases, HOOOH-B (B = acetone and dimethyl ether), strongly retards the decomposition in these bases as solvents, most likely by preventing such a proton transfer....
The residue obtained from the acetone extract by solvent evaporation was first partitioned between water and AcOEt. From the organic layer, BTX-B3 5 and BTX-B4 6 were obtained while BTX-B2 4 was retained in the aqueous layer and then extracted with BuOH <1995TL8995, 1998T735, 1999MI45>...
40 utilized an acetone-ethanol (50:50, v/v) seed extract from a Tunisian cultivar. The study reported MIC values ranging between 0.78 and 3.125 mg/ml and MBC values ranging between 1.56 and 12.48 mg/ml. It is noteworthy that although several studies have explored alcohol and aqueous ...
Indeed, when C-subunit is not complexed with PHB and polyP, this protein likely dissolves in the acetone phase during the dehydration step and is therefore not present in the pellet used for channel extraction by chloroform. In contrast, when the C-subunit associates with polyP and PHB, this...
