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

Are covalent molecular compounds soluble?
Solubility of a substance in water depends on the type of interaction predominates in the compound and the solvent.The solubility of any compound follows the principle "like dissolves like".So if a covalent molecular compound is polar then it dissolves in a polar solvent and if it is non polar or hydrophobic then it dissolves in a nonpolar solvent

How do you tell if a molecular compound is polar or not?
A molecular compound is considered polar if the individual bond dipoles do not cancel each other out due to molecular symmetry. One way to determine if a compound is polar is to look at the electronegativity difference between the atoms in the bond: if there is a significant difference, the bond is likely polar. Additionally, the molecular shape and symmetry can also influence polarity.
Why are some materials insoluble?
Some materials are insoluble in certain solvents because their molecular structure does not allow them to be easily integrated into the solvent molecules. This can be due to differences in polarity, charge, or size between the material and the solvent. Additionally, some materials may form strong intermolecular bonds that prevent them from breaking apart and dissolving in a given solvent.
What is the least polar organic solvent and why?
The least polar organic solvent must not have any dipole interactions. It can either have all hydrocarbons or have perfect symmetrical molecular structure that cancels out opposing electronegative forces. Hexane would be the least polar organic solvent available.

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.
Is sodium chloride is soluble in ether?
Sodium chloride is highly polar (ionic in fact) where hexane is very not. The two don't attract at all, so each is insoluble in the other.

Is IF polar or non polar?
yes it is the bond is polar, and the linear shape allows for polarity, F is negative

Are kerosene and oil soluble?
No. Kerosene is an organic compound. and water is a non-organic compound. (kerosene : non-polar Water : polar). As water is a polar solvent kerosene is not soluble in it. but kerosene is soluble in ethyl alcohol which is a non-polar solvent.
Why does acetone have less cohesion than water?
"Molecular Bonds"? They don't. Your question makes no sense.
Why is salt a soluble?
Because NaCl is a polar compound (solute) dissolved in a polar solvent (water).
Is iron III nitrate soluble in hexane?
No, it is an ionic compound which is soluble in water (a polar solvent) but not in Hexane ( a non polar solvent).
Why sodium chloride dissolved in water'?
Water is a polar solvent and NaCl is an ionic compound.
Why water is a polar compound?
A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms.
