Phosphonium: Applications, Types of phosphonium cations & Uses

In chemistry, the term phosphonium (more obscurely: phosphinium) describes polyatomic cations with the chemical formula PR+4 (where R is a hydrogen or an alkyl, aryl, organyl or halogen group). These cations have tetrahedral structures. The salts are generally colorless or take the color of the anions.
