  2. Sulfur forms over 30 solid allotropes, more than any other element. Besides S 8, several other rings are known. Removing one atom from the crown gives S 7, which is more of a deep yellow than the S 8. HPLC analysis of 'elemental sulfur' reveals an equilibrium mixture of mainly S 8, but with S 7 and small amounts of S 6.
  3. Sulfur is mentioned 15 times in the Bible, and was best known for destroying Sodom and Gomorrah.It was also known to the ancient Greeks, and burnt as a fumigant. Sulfur was mined near Mount Etna in Sicily and used for bleaching cloth and preserving wine, both of which involved burning it to form sulfur dioxide, and allowing this to be absorbed by wet clothes or the grape juice.
  4. The orbital diagram for sulfur has seven boxes with two arrows pointing in opposite directions and two boxes with one arrow pointing up in each. The arrows represent the 16 electrons of the sulfur atom, and the directions represent their spins. The boxes represent sulfur's orbitals. Sulfur's electron configuration is 1s 2 2s 2 2p 6 3s 2 3p 4.

Study Notes

The chemistry of sulfur‑containing organic compounds is often omitted from introductory organic chemistry courses. However, we have included a short section on these compounds, not for the sake of increasing the amount of material to be digested, but because much of the chemistry of these substances can be predicted from a knowledge of their oxygen‑containing analogues.

A thiol is a compound which contains an $ce{-}$SH functional group. The $ce{-}$SH group itself is called a mercapto group. A disulfide is a compound containing an $ce{-}$S$ce{-}$S$ce{-}$ linkage.

(Organic) sulfides have the structure R$ce{-}$S$ce{-}$R′, and are therefore the sulfur analogues of ethers. The nomenclature of sulfides can be easily understood if one understands the nomenclature of the corresponding ethers. Notice that the term “thio” is also used in inorganic chemistry. For example, SO42− is the sulfate ion; while S2O32−, in which one of the oxygen atoms of a sulfate ion has been replaced by a sulfur atom, is called thiosulfate.

Thiolate anions, RS$ce{-}$, are analogous to alkoxy anions, RO$ce{-}$. Thiolate anions are better nucleophiles than are alkoxy anions.

If you have trouble understanding why trialkylsulfonium ions are formed, think of them as being somewhat similar to the hydronium ions that are formed by protonating water:

Sulfur

Later we shall see examples of tetraalkylammonium ions, R4N+, which again may be regarded as being similar to hydronium ions.

Sulfoxides and sulfones are obtained by oxidizing organic sulfides. You need not memorize the methods used to carry out these oxidations.

Table 18.1, below, provides a quick comparison of oxygen‑containing and sulfur‑containing organic compounds.

Note that when we name thiols, we include the “e” of the alkane name. Thus, CH3CH2SH is called “ethanethiol,” not “ethanthiol.”
