Which species would react fastest with electrophiles? How are enolate ions prepared? How are enolate ions prepared? Are enolate ions formed when a weaker base is used? Water is about 10,000 more acidic than a C=O compound. Hydroxide is about 10,000 less basic than an enolate. Are enolate ions formed when a weaker base is used? Can these enolate ions be used in reactions? Water is about 10,000 more acidic than a C=O compound. Hydroxide is about 10,000 less basic than an enolate. Can these enolate ions be used in reactions?
