The concepts used to solve this problem is the synthesis of enolate ion from ketone under basic conditions. The enolate ions are resonance stabilized. It has two forms, namely carbanion, and an oxyanion.
Show the formation of carbanion and oxyanion by removing each different .
Enolate ion:
It is an ion which is formed by removing from aldehyde and ketone. It can be formed both in acidic and basic condition.
The mechanism of the synthesis of enolate is shown below.
The mechanism of the synthesis of enolate is shown below.
The oxyanions formed from the ketone under basic condition are as follows.
