Why is benzophenone not soluble in water?
Benzophenone was insoluble in water because water is a polar molecule. Like dissolves like, and since benzophenone is nonpolar, the result was insoluble. It has no polar functional groups to make it slightly polar, it is completely nonpolar.
Is benzophenone soluble or insoluble?
Solubility: Practically insoluble in water, but soluble in organic solvents such as alcohol, acetone, ether, acetic acid, chloroform and benzene.
Why is benzophenone insoluble in methanol?
Methanol has an intermediate polarity; however, it can dissolve benzophenone because the polar carbonyl group on benzophenone can make hydrogen bond to the methanol; therefore, making benzophenone soluble in methanol.
Why is benzophenone weakly polar?
Since methyl alcohol is somewhat polar, the more polar benzophenone is more soluble in methyl alcohol than biphenyl. Also, benzophenone can make hydrogen bonds. The molecule has many more nonpolar bonds than polar bonds, so overall the molecule is considered as nonpolar (or only very slightly polar).
Why is octanol insoluble in water?
1-octanol with water is insoluble because even though the –OH group in 1-octanol is polar the long carbon chain (non-polar) over powers the polarity making it repel the polar water molecules. But the carbon chain, which is non-polar, make it repel the water, but not as much, making it partially soluble.
What foods contain benzophenone?
Benzophenone occurs naturally in some foods (such as wine grapes and muscat grapes) and is added to other foods as a flavoring. In personal care products, benzophenone is used as a fragrance enhancer or to prevent products such as soaps from losing scents and colors in the presence of UV light.

Can you make a 27% solution of 1-octanol in water?
Terms in this set (11) Is it possible to make a 27% solution of 1-octanol in water? No, it is a compound with more than four carbons, so it is insoluble in water.
Why is benzophenone insoluble in methyl alcohol?
Benzophenone is insoluble in water because water is a polar solvent. Benzophenone contains a polar carbonyl group that forms the hydrogen bonding with the OH group of methyl alcohol. So due to this intermolecular hydrogen bonding benzophenone is soluble in methyl alcohol.
Which is soluble in water benzophenone or hexane?
Benzophenone, which is largely nonpolar, but possesses a polar carbonyl group, was found to be partially soluble in methyl alcohol and hexane but insoluble in water. Malonic acid, a polar molecule that is also able to ionize, was found to be soluble in water and methyl alcohol but insoluble in hexane.
Why is benzoic acid insoluble in water?
Benzoic acid is insoluble in water because it has the large nonpolar benzene ring in the structure, which water cannot dissolve. All three of these molecules are able to form hydrogen bonds, which is important in solubility. Beside above, why organic compounds are insoluble in water?
How is benzophenone broken down in the environment?
Benzophenone can migrate to food from packaging printed with UV-cured inks, either by direct contact or by benzophenone vapors. If benzophenone is released to the environment it will be degraded in air. It may be broken down by light. It will volatilize from soil and water surfaces. Benzophenone is expected to be mobile in soil.
