Formamide is the most polar solvent. It has a dipole moment of 3.73 and a dielectric constant of 109. As a comparison, water has a dipole moment of 1.85 and a dielectric constant of 80. The higher the dipole moment value and the dielectric constant, the more polar the solvent. At the opposite, the less polar solvents are hexane, benzene and carbontetrachloride.

How polar and non polar bonds affect solubility?
Molecules with many polar bonds are soluble in polar solvents.Also, molecules with none or few polar bonds (many non-polar bonds) are soluble in non-polar solvent. e.g Water is a polar solvent so substances with many polar bonds are soluble in it.
A compound has a very high Rf value in a polar solvent what can you say about its molecular structure?
Rf Value - It tells you the affinity that the compound has to the solvent...High Rf = little or no polar groups and low Rf = more polar groups. Question: In TLC (thin-layer chromatography) when the compound has a high Rf the solvent is: a. less polar b. Is more polar Answer: a. less polar
Why does Br2 dissolve in cyclohexane and not in water?
Bromine is more soluble in hexane than water. Br2 is non polar so it dissolves good in an non polar solvent like hexane. Water is a polar solvent.
Can a non polar solute dissolve nonpolar solvent?
Yes, like dissolves like so a nonpolar solvent dissolves nonpolar solutes and polar solvents dissolve polar solutes
Is H2O a solvent?
Yes it is a solvent.Iht is a polar solvent.
What are the Differences between polar solvent and non polar solvent?
A polar solvent is a compound which has dipole moments which allow compounds which are able to form ion-dipole moments to dissolve. Non-polar solvent refers to compounds which have no polarity,(no dipole moments, or that the polarity is cancelled out), such as CCl4.
Is cyclohexane a polar solvent or a non- polar solvent?
Cyclohexane is a non polar solvent.
Is cyclohexane a polar solvent or a non polar solvent?
It is nonpolar
What does a polar solvent dissolve in?
a polar solvent dissolves a non polar solute

What property of water affects solubility?
growl Water is not conventionally thought of as a solute, because it is much more practical as a solvent. That said, I assume the intended question was which property of water makes it an ideal solvent in some cases but not others? Water is a polar molecule, so acts as an ideal solvent for polar molecules, and an ineffective solvent for non-polar molecules. That is, polar molecules are readily soluble in water, but non-polar molecules (for all practical purposes) are insoluble in water. "Like dissolves like."
Why does Br2 dissolve in cyclohexane and not in water?
Bromine is more soluble in hexane than water. Br2 is non polar so it dissolves good in an non polar solvent like hexane. Water is a polar solvent.
Is water a non-polar solvent?
No, water is a polar solvent because of the polar oxygen-hydrogen bonds and the geometry of the compound.
What type of solvent is best suited to dissolve ionic or highly polar substance?
The type of solvent that is best suited to dissolve an ionic or a highly polar solvent would also be highly polar, probably a polar protic solvent like water or alcohol.
Can a non polar solute dissolve nonpolar solvent?
Yes, like dissolves like so a nonpolar solvent dissolves nonpolar solutes and polar solvents dissolve polar solutes
Is H2O a solvent?
Yes it is a solvent.Iht is a polar solvent.
