  • You can get pi-pi attraction with aromatic solvents and solutes, I believe. One would not expect glucose to dissolve in hexane . O. 5. Electronegativity. OH. Polar. Figure 1. 0. There are 9 polar carbons, but 42 non polar C's. Liquids. CH2OH. Freely soluble in water, in 0. Solubility & Miscibility. Revised: 1/13/15. Cl: 3. The like dissolves like rule applies also to solutions made from the same or different phases of matter. Because I 2 is intensely purple and quite soluble in both CCl 4 and hexane, but insoluble in water, a small amount of I 2 has been added to help identify the hexane and CCl 4 layers. 2. Answer to why is glucose soluble in water but is not soluble in hexane?Glucose is essentially insoluble in nonpolar organics like benzene or hexane because the opposing polarities of the solvents repels the molecules and does not allow for glucose dissolution. H: 2. Carbon. O: 3. Nonpolar. Polar organics like acetone or isopropanol or ethanol (or vodka) will dissolve it because you get hydrogen bonding that hold the molecules in solution. Water. Candelilla . The nonpolar Its saturated solution has a pH of about 3. Slightly soluble in water; very soluble in alcohol, in chloroform, and in ether; freely soluble in carbon disulfide, in solvent hexane, and in fixed and volatile oils. We know water Glucose dissolves in water because polar water molecules attach to the glucose molecules. H2N. Dantrolene Sodium: Fine orange to . glucose=polar with the O-H groups and hydrogen bondings hexane=non-polar. Urea. C. Triglycerides are the major type of substance in vegetable oils. Ionic solids (salts) dissolve in water but not in hexane. Glucose has a lot of hydroxyls. 9% sodium chloride solution, and in 5% dextrose solution; soluble in methanol; very slightly soluble in dehydrated alcohol. Is odorless and sweet-tasting. 1. Chloroform. Nonpolar compounds like napthalene dissolve in hexane but not in water. Hexane is a non polar solvent. Glucose. Acetone. It is insoluble in water and soluble in hexane. Glucose is a polar molecule. Dissolving occurs because no, it is in soluable in hexane. C: 2. Dextrose Excipient: Colorless crystals or white, crystalline or granular powder. Slightly soluble in water and in isopropanol; freely soluble in chloroform; soluble in methanol; sparingly soluble in alcohol and in acetone; practically insoluble in ether and in solvent hexane. Fructose. Jan 13, 2015 Hexane. Tetrachloride. It depends. Polar molecules like sugar dissolve in water but not in hexane. 3. Consequently, glucose is very soluble in water (91 g/120 mL of water) but essentially insoluble in nonpolar solvents such as benzene. Glucose is essentially insoluble in nonpolar organics like benzene or hexane because the opposing polarities of the solvents Jan 13, 2015 Hexane. Practically insoluble or insoluble in water and in hexane; freely soluble in chloroform; soluble in acetone; sparingly soluble in alcohol and in benzene; slightly soluble in ether. Sucrose. NH2. We arrive at the following conclusions: 'like dissolves like"; substances that are mostly polar (like glucose) dissolve in polar solvents like water but not in a nonpolar glucose=polar with the O-H groups and hydrogen bondings hexane=non-polar. The many O-H Organic compounds like n-hexane, C6H14, and dodecane, C12H26, are miscible in one another. Lets review these ideas by looking at what happens when sugar dissolves in water
