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.
Which solevent would be on top hexane or water?
Water would be on top of hexane in a mixture because water is denser than hexane. In a typical scenario, when the two liquids are combined, the less dense hexane will float on top of the denser water. This separation occurs due to their differing polarities, as water is polar and hexane is nonpolar.
Why is CuSO4 more soluble in water than in organic solvent?
CuSO4 is ionic and water is polar. The types of bonding allow water to dissolve the salt much more easily than an organic solvent (e.g. alcohol, hexane) could.
What determines whether a compound will be more soluble in hexane or in H2O?
Calcium Carbonate Some compounds are amphipathic. Water is a polar solvent and hexane is a nonpolar solvent. For a compound to dissolve in both, it would need to posses some nonpolar properties and some polar properties.
Why does hexane appear as more than one peak in gas chromatography?
Hexane is a mixture of 3 isomers out of a possible 5 isomers of 6 carbon alkanes. Normally there are 3 peaks for GC. Use a GC grade n-Hexane for one peak of the 'main' hexane.
Is hexane or chloroform more polar?
chloroform is more polar than hexane. Based from the solvent polarity chart, alkyl halides (such as CHCl3) are relatively more polar than alkanes (such as hexane). Moreso, alkanes tend to be the least polar among the organic and inorganic compounds due to their hydrocarbon structure.
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.
Why is potassium manganate 7 more soluble in hexane than water?
Potassium manganate 7 is more soluble in hexane than in water because it is a nonpolar solvent like hexane. Nonpolar solutes tend to dissolve better in nonpolar solvents, while water is a polar solvent. Therefore, the solubility of potassium manganate 7 is higher in hexane than in water.
Is caffeine more miscible in organic layer (dichloromethane) or aqueous layer?
Caffeine is more miscible in the organic layer (dichloromethane) than in the aqueous layer. This is because caffeine is a non-polar compound and thus dissolves better in organic solvents than in water, which is a polar solvent.
Why is sodium chloride more soluble in water than in hexane?
Because water is a polar solvent.
Which Is more soluble hexane benzene ethanol?
Ethanol is more soluble than hexane and benzene in water due to its polar nature. Hexane and benzene are nonpolar compounds and have low solubility in water.
Is isobutene more soluble in water or hexane?
Isobutene is more soluble in hexane than in water. This is because isobutene is a nonpolar molecule, making it better able to dissolve in nonpolar solvents like hexane than in polar solvents like water.
Why use dichloromethane instead of ethanol to extract trimyristin?
Dichloromethane is often preferred over ethanol for extracting trimyristin because it is a non-polar solvent that can effectively dissolve the target compound. Additionally, dichloromethane has a lower boiling point than ethanol, making it easier to separate from the extracted trimyristin. Lastly, dichloromethane is less polar than ethanol, which can lead to a more efficient extraction process.
Which one is more polar ie Chloroform or DCM?
Chloroform is more polar than dichloromethane (DCM) due to the presence of a stronger dipole moment caused by its more electronegative chlorine atoms. This makes chloroform more soluble in polar solvents compared to DCM.
Is benzene more soluble in hexane than glycerol?
Yes, benzene is more soluble in hexane than in glycerol because they have similar nonpolar properties. Benzene is a nonpolar compound, and hexane is a nonpolar solvent, making them more compatible. Glycerol, on the other hand, is a polar compound and can have limited solubility for nonpolar substances like benzene.
Why did the caffeine leave the water and move into the dichloromethane?
Caffeine is more soluble in dichloromethane than in water due to differences in their polarity. When caffeine is added to the water-dichloromethane mixture, it is preferentially dissolved in dichloromethane, which is a non-polar solvent. This movement is driven by the principle "like dissolves like", where compounds tend to dissolve in solvents with similar polarity.
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.
