Understanding Mustard Gas Identification

Mustard Gas, a notorious chemical warfare agent, is known for its vesicant (blistering) properties affecting skin, eyes, and respiratory systems. Identifying its correct chemical name is important for understanding its nature.

Chemical Breakdown of Options

The question requires identifying the chemical compound that represents Mustard Gas from the provided options:

• Option 1: Uranium hexafluoride

  Uranium hexafluoride (UF₆) is a compound crucial for nuclear fuel processing, particularly uranium enrichment. It is not related to Mustard Gas.

• Option 2: Dichlorodiphenyltrichloroethane

  This compound is widely recognized as DDT, a synthetic insecticide. Although it contains chlorine atoms, DDT is chemically distinct from Mustard Gas.

• Option 3: 2,2'-dichlorodiethylsulfide

  This is the specific chemical name for sulfur mustard, the substance commonly referred to as Mustard Gas. Its structure involves two chloroethyl groups linked by a sulfur atom.

• Option 4: Diethylsulphoxide

  Diethylsulphoxide is an organosulfur compound, often used as a solvent. It does not possess the properties or structure of Mustard Gas.

Correct Chemical Identity of Mustard Gas

After reviewing the options, the chemical identity corresponding to Mustard Gas is 2,2'-dichlorodiethylsulfide. This compound is infamous for its use as a chemical weapon due to its severe blistering effects.
