Chemistry:Lyate ion

Short description: Negatively-charged ion made by deprotonating a solvent molecule

In chemistry, a lyate ion is the anion derived by the deprotonation of a solvent molecule. For example, a hydroxide ion is formed by the deprotonation of water, and methoxide (CH
3O−
) is the anion formed by the deprotonation of methanol.

Its counterpart is a lyonium ion, the cation formed by the protonation of a solvent molecule.

Lyonium and lyate ions, resulting from molecular autoionization, contribute to the molar conductivity of protolytic solvents.
