What is the Difference Between Sulfone and Sulfoxide?
🆚 Go to Comparative Table 🆚Sulfone and sulfoxide are organic compounds containing sulfur atoms. The key difference between them is the number of double-bonded oxygen atoms in their respective functional groups:
- Sulfone: Contains a sulfonyl functional group (R−S(=O)2−R’) with two double-bonded oxygen atoms and a central hexavalent sulfur atom. Sulfones are typically prepared by organic oxidation of thioethers, often referred to as sulfides. They are relatively inert functional groups, being weakly basic compared to sulfoxides.
- Sulfoxide: Contains a sulfoxide functional group with only one double-bonded oxygen atom. Sulfoxides are intermediates in the synthesis of sulfones from thioethers. They have a lone pair of electrons on the sulfur atom, making the sulfoxide group nonplanar. Most sulfoxides are colorless liquids or solids with low melting points.
In summary, sulfones have two double-bonded oxygen atoms in their sulfonyl functional group, while sulfoxides have only one double-bonded oxygen atom in their functional group.

Comparative Table: Sulfone vs Sulfoxide
Here is a table comparing the differences between sulfone and sulfoxide:
Property | Sulfone | Sulfoxide |
---|---|---|
Definition | Sulfone is an organic compound containing a sulfonyl functional group attached to two carbon atoms, with a central sulfur atom having two double-bonded oxygen atoms. | Sulfoxide is an organic compound containing a central sulfur atom attached to two carbon atoms, with one double-bonded oxygen atom and one single-bonded oxygen atom. |
Sulfur Atom Oxidation State | +6. | +6. |
S=O Bonds | Two double-bonded S=O bonds. | One double-bonded and one single-bonded S=O bond. |
Acidity | Sulfones tend to be more acidic than sulfoxides. | Sulfoxides are less acidic than sulfones. |
Reactions | Sulfones can be obtained by oxidizing sulfoxides. | Sulfoxides can be obtained by oxidizing sulfides. |
Both sulfone and sulfoxide are organic compounds containing a central sulfur atom. However, the key difference between them is the number of double-bonded oxygen atoms attached to the sulfur atom: sulfones have two double-bonded oxygen atoms, while sulfoxides have only one.
