Q:

What is an enolate ion?

A:

Quick Answer

An enolate ion is a negative ion which is obtained by removing the hydrogen atom from ketone. Enolate ions can take two forms: one with a negative charge on the carbon atom and one having negative charge on the oxygen atom. Enolate ion consists of three atoms. The charge is distributed on the three atoms, which is how the enolate ion remains stable.

Full Answer

An enolate is an intermediate form of enol. The process of creation of enol in base catalyst has an intermediate stage where enolate is formed. In order to fully understand the formation of enol, the formation of enolate, or vice versa, must be taken into consideration. In aqueous solutions, ketone loses its hydrogen atom in water. The resulting carbonyl compound is known as enolate. Enolates are prepared with the help of using a base. The majority of the charge in an enolate anion is on O; however, the charge can be either on carbon atom (C) or on oxygen atom (O). In both the cases, the charge on the atoms is always negative. This is the reason that enolates are known as ions since they carry negative charge. All in all, enolate ions are negative ions that are formed as an intermediate process.
