In the 1980s, there was an international agreement to destroy all stockpiles of mustard gas, ClCH₂CH₂SCH₂CH₂Cl. When this substance contacts the moisture in eyes, nasal passages, and skin, the -OH groups of water replace the Cl atoms and create high local concentrations of hydrochloric acid, which cause severe blistering and tissue destruction.
The balanced equation for this reaction, and calculate ΔHrxn°
RbCL<CH3OH< CH3Cl< CH4
What is mustard gas?
A sort of chemical weapon is sulfur mustard. On contact, these substances cause blistering of the skin and mucous membranes. They are also known as blistering agents or vesicants. Sulfur mustard is also referred to as "mustard gas or mustard agent," or by the letters H, HD, and HT in the military.
Having the chemical formula C4H8Cl2S, dichlorodiethyl sulfide is a symmetric, short chain molecule with a sulfur atom in the centre and chlorine atoms at both ends. In a broader sense, mustards are substances with the structural formula BC2H4X, where X is any leaving group and B is a Lewis base. As a result, cyclic -onium ions may develop (sulfonium, ammonium, etc.)
