Disulfur dichloride is a yellow liquid that fumes in moist air due to reaction with water: 16 S 2 Cl 2 + 16 H 2 O → 8 SO 2 + 32 HCl + 3 S 8. It is produced by partial chlorination of elemental sulfur.
Sulfur dichloride is the chemical compound with the formula SCl 2. This cherry-red liquid is the simplest sulfur chloride and one of the most common, and it is used as a precursor to organosulfur compounds. It is a highly corrosive and toxic substance, and it reacts on contact with water to form chlorine-containing acids.
Sulfuryl chloride is an inorganic compound with the formula SO 2 Cl 2. At room temperature, it is a colorless liquid with a pungent odor. Sulfuryl chloride is not found in nature, as can be inferred from its rapid hydrolysis. Sulfuryl chloride is commonly confused with thionyl chloride, SOCl 2.
It thus tends to form a covalent bond with another S − center to form S 2− 2 group, similar to elemental chlorine existing as the diatomic Cl 2. Oxygen may also behave similarly, e.g. in peroxides such as H 2 O 2. Examples: Hydrogen disulfide (S 2 H 2), the simplest inorganic disulfide; Disulfur dichloride (S 2 Cl 2), a distillable liquid.
Treatment of sulfur with hydrogen gives hydrogen sulfide.When dissolved in water, hydrogen sulfide is mildly acidic: [5] H 2 S ⇌ HS − + H +. Hydrogen sulfide gas and the hydrosulfide anion are extremely toxic to mammals, due to their inhibition of the oxygen-carrying capacity of hemoglobin and certain cytochromes in a manner analogous to cyanide and azide.
Thionyl chloride is an inorganic compound with the chemical formula SOCl 2.It is a moderately volatile, colourless liquid with an unpleasant acrid odour.Thionyl chloride is primarily used as a chlorinating reagent, with approximately 45,000 tonnes (50,000 short tons) per year being produced during the early 1990s, [5] but is occasionally also used as a solvent.
The structural formula is supposed to contain two mercury atoms bound to each other, as in the real compound mercury(I) chloride (calomel), Hg 2 Cl 2. The latter is an ionic compound with the dimercury(I) cation, Hg 2+ 2 or + Hg–Hg +, and chloride anions Cl −. However, like cinnabar, Hg 2 S may be a covalent polymer [–S–Hg–Hg–]
Disulfur difluoride has a chain structure F−S−S−F.The angle between the F a −S−S and S−S−F b planes is 87.9°, while the angles of F a −S−S and S−S−F b are equivalent, and are equal to 108.3°.
