Stereochemistry and Isomerism

Stereochemistry deals with the three-dimensional structure and properties of molecules. It explains the arrangement of atoms and their manipulation within a molecule in a 3D structure. Stereochemistry can be dealt with all types of molecules. Based on the stereochemistry of a molecule, the physical and chemical properties of the molecules vary.

Would you explect RDX dust from an explosion to react with diphenylamine to produce a deep blue dye? RDX equation: C3H6N6O6 (s) -> 3CO (g) + 3H2O (g) + 3N2 (g) Because virtually all explosives and propellants use nitrogen based oxidizers, chemical identification can be straight forward. Diphenylamine, (C6H5)2NH, will react with nitrate or nitrite (or other oxidizers) in the residue to form diphenylbenzidine blue.
