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

What is a phosphonium ylide?
Phosphonium ylide: An ylide in which the positive formal charge end is a tetravalent phosphorous atom.
Why is PH4+ tetrahedral?
Answer: P in both PH3 and PH4+ is hybridized. Due to the absence of lone pair-bond pair repulsion and presence of four identical bond pair-bond pair interactions, PH4+ assumes tetrahedral geometry with a bond angle to 109° 28′.

How is ylide formed?
Ylides can be synthesized from an alkyl halide and a trialkyl phosphine. Typically triphenyl phosphine is used to synthesize ylides. Because a SN2 reaction is used in the ylide synthesis methyl and primary halides perform the best. Secondary halides can also be used but the yields are generally lower.
