Why is sugar not dissolving in oil?

Answer 1

Oil has only C-H (carbon-hydrogen) bonds, which are nonpolar. Sugar has only C-OH bonds, which are polar. That is, there is a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen. Thus, sugar molecules are strongly attracted to other sugar molecules, but not at all to oil molecules.

Sugars are generally highly soluble in polar solvents, such as water. Slightly polar solvents, such as alcohols, will dissolve some sugars but not others.

This is partly a matter of hydrogen bonding, in which the positive hydrogens of one molecule are attracted to the negative oxygens of another, and partly a matter of dielectric constant: Polar solvents have high dielectric constants, enabling charges to be separated without much added energy.

Answer 2

Sugar is a polar substance, meaning that parts of the molecule have partial positive and negative charges, and will usually only dissolve in another polar substance such as water.

Oil is nonpolar and will generally only dissolve other nonpolar substance. The rule of thumb is "like dissolves like."

Answer 3

Sugar does not dissolve in oil because oil is a nonpolar substance, while sugar is a polar substance. Substances that are polar, like sugar, are capable of dissolving in water, which is also a polar substance. Since oil and sugar have different polarities, they are not compatible for dissolving into each other.

Answer 4

No, because the particles of the sugar only react to water, not oil

Answer 5

no yes it does not dissolve into oil for sure

Answer 6

No, sugar does not dissolve in oil.

Answer 7

no
