The structure of the sulfuryl group
The sulfuryl group is a functional group in inorganic chemistry consisting of a sulfur atom covalently bound to two oxygen atoms (O2SX2).
It occurs in compounds such as sulfuryl chloride, SO2Cl2 and sulfuryl fluoride, SO2F2.
In organic chemistry, this group is found in sulfones (RSO2R') and sulfonyl halides (RSO2X), where it is called the sulfonyl group.
