Why does naphthalene dissolve in organic solvents but does not dissolve in water?

naphthalene is only made of two types of atom: carbon and hydrogen. There is little difference in electronegativity between these atoms (how well they can pull on electrons) so there is an equal distribution of electron density across the molecule, thus being NON-POLAR.
Water on the other hand is comprised of oxygen and hydrogen atoms, between which there is a large difference in electronegativity. This means that there is an imbalance of charge across the molecule resulting in water being POLAR.
a polar molecule is unable to interact with a non-polar molecule as they don't 'have anything in common' in terms of their charge distribution.
Naphthalene will dissolve in petrol due to petrol being a non-polar solvent.

What does so2 dissolve in?
SO2 dissolves in water to form sulfurous acid (H2SO3). It can also dissolve in organic solvents like ethanol.
Is naphthalene soluble to ethyl alcohol?
Yes, naphthalene is sparingly soluble in ethyl alcohol. It has low solubility in most organic solvents, including ethyl alcohol.
What will lipids dissolve in?
Lipids are insoluble in water but can dissolve in organic solvents such as alcohol, ether, chloroform, and acetone. These solvents break down the nonpolar interactions between lipid molecules, allowing them to dissolve.
Does ionic compounds dissolve in organic solvent?
Ionic compounds typically do not dissolve well in organic solvents because organic solvents are nonpolar and ionic compounds are held together by strong electrostatic forces between positive and negative ions. These strong forces are not easily disrupted by the weak Van der Waals forces present in organic solvents, making it difficult for ionic compounds to dissolve.
What solvent does not dissolve ionic compounds?
Nonpolar solvents, such as hexane and benzene, do not dissolve ionic compounds because they lack the ability to dissociate the ions due to their nonpolar nature. Ionic compounds require polar solvents, such as water or alcohols, to dissolve and dissociate into their constituent ions.
What is the difference in the solubility of organic and inorganic compounds in water and in organic solvents?
In general, inorganic compounds will dissolve in polar or inorganic solvents such as water, whereas organic compounds will dissolve in organic solvents. However there are many exceptions to these.
Why is naphthalene more soluble in petroleum ether than in water?
naphthalene is non-polar and can only dissolve in non-polar solvents. ether is non-polar, water is polar.
Is naphthalene soluble to ethyl alcohol?
Yes, naphthalene is sparingly soluble in ethyl alcohol. It has low solubility in most organic solvents, including ethyl alcohol.
Why phenol does not dissolve in water when excess?
Phenol (C6H5OH) is more organic and is a covalent compound. The percentage of carbon is more compared to -OH (the polar part). Hence phenol will dissolve in organic solvents and not in water.
What do solvents do to you?
Solvents are chemical substances that can dissolve, suspend or extract other materials usually without chemically changing either the solvents or the other materials. Solvents can be organic, meaning the solvent contains carbon as part of its makeup, or inorganic, meaning the solvent does not contain carbon. For example, "rubbing" alcohol is an organic solvent and water is an inorganic solvent. Hydrocarbon and oxygenated solvents are examples of types of organic solvents that can effectively dissolve many materials.
How do you account for the observed solubility of naphthalene and sodium chloride in water and ether based on the nature of the bonds that exist in them?
The reason why naphthalene can be dissolve in ether and not in water is because of their polarity. Naphthalene is a non-polar molecule. so it can only dissolve with a non-polar molecule.
Is naphthalene soluble in water or hexane?
Naphthalene is strictly non-polar with a structure similar to two benzene rings linked together. Similarly ether is also highly non-polar. Since like dissolves like naphthalene is soluble in ether.
What is the generalization of solubility of lipids?
Lipids are soluble in nonpolar or organic solvents.
How can we separate naphthalene from sand?
One way is to dissolve the ammonium chloride in water, then recover the ammonium chloride by evaporation; the naphthalene will not dissolve in water in any substantial quantity.
Is carvacrol water-soluble?
Yes, carvacrol is partially water-soluble. It can dissolve in water to some extent but is more soluble in organic solvents like alcohol and oils.
Why is KNO3 and CCL4 not miscible?
KNO3 is potassium nitrate. It is an IONIC compound which dissolved in water. CCl4 is tetrachloromethane, it is a COVALENT compound, which is misxible in organic solvents.
How do you account for the observed solubility of naphthalene and sodium chloride in water and in ether based on the nature of the bonds that exist in them?
The reason why naphthalene can be dissolve in ether and not in water is because of their polarity. Naphthalene is a non-polar molecule. so it can only dissolve with a non-polar molecule.
