Why does hexane not form a solution with water?
Water is a polar molecule (is a dipole, has a positive end and a negative end), hexane is a non-polar molecule. Like dissolves like. Water will dissolve other polar molecules, like HCl and NH3. Hexane will dissolve non-polar molecules like benzene or toluene.
Which of the following liquids is hexane most likely to dissolve?
NaCl will not dissolve in Hexane because NaCl is a polar molecule and Hexane is a non-polar molecule. NaCl is insoluble in Hexane. On the other hand, NaCl will dissolve in water because both are polar molecules. "Like dissolves like".
How do you explain sodium chloride is soluble in water but not in hexane?
Sodium chloride is soluble in water because both have polar molecules; but not in hexane becuse it is nonpolar.
What color of iodine mixing with hexane?
When iodine is mixed with hexane, it typically results in a violet or purple color in the hexane layer. This occurs because iodine is more soluble in non-polar solvents like hexane compared to polar solvents. The distinct color is due to the formation of iodine molecules that are dissolved in the hexane, which reflects the characteristic color of iodine.
Which liquid has a higher surface tension glycerol or hexane?
Glycerol has a higher surface tension compared to hexane. This is because glycerol is more polar than hexane, leading to stronger intermolecular forces between glycerol molecules which results in a higher surface tension.
Why is naphthalene soluble in hexane?
Naphthalene is soluble in hexane because both substances are nonpolar. Naphthalene molecules are attracted to the nonpolar hexane molecules through London dispersion forces, allowing them to mix and form a homogeneous solution.
Is cholesterol more soluble in water or hexane?
Hexane is a non-polar chain hydrocarbon; on the principle of "like dissolves like" hexane will dissolve other non-polar compounds quite well. Water is a polar molecule, as are all halogens as exemplified by the simplest common halogen of all, hydrochloric acid. Halogen acids, common refrigerants, even some anesthetics are all polar molecules and therefore dissolve fairly well in other polar liquids, including water.
Why is hexane insoluble in water and methylene chloride is soluble in water?
Hexane is insoluble in water because it is non-polar, so it cannot form hydrogen bonds with water molecules. Methylene chloride, on the other hand, is soluble in water because it can form hydrogen bonds with water molecules due to its polar nature.
What compound most dissolve in hexane?
Hexane is a non-polar solvent, so it will not dissolve in water. Kerosene is non-polar so it will dissolve in Hexane.
Is toluene or hexane hygroscopic?
Neither toluene nor hexane are hygroscopic, as they do not readily absorb or attract water from the atmosphere. They are both non-polar solvents and typically do not form strong interactions with water molecules.
Is hexane more polar than dichloromethane?
No, hexane is less polar than dichloromethane. Hexane is a nonpolar solvent because it contains only carbon and hydrogen atoms, while dichloromethane has polar covalent bonds due to the presence of chlorine atoms.
Is hexane or methanol more polar?
Ethanol is polar, as the non-polar OH group still exerts enough force over the rest of the chain to make the entire hydrocarbon dissolve. This trend continues with alcohols with one carbon (methanol) two carbons (ethanol) three carbons (propanol) and four carbons (butanol). However, butanol is only polar when the OH functional group is attached to a secondary carbon (i.e. butan-2-ol) Hexane is always non-polar, as it is a symmetrical hydrocarbon (like most of them) which means that all forces cancel each other out. So ethanol is more polar than hexane.
