"Viologen" Pronounce,Meaning And Examples

"Viologen" Meaning

Viologen is a class of organic compounds consisting of a benzidine-based structure with one or more quaternary ammonium salt groups attached to the benzene ring. The term "viologen" was first used in 1889 to describe the chemical structure of a particular compound. Viologens are typically blue or purple cations and are known for their electrochemical properties, particularly their ability to act as electron acceptors and to reversibly change their oxidation state.
