Enolate formation question
« on: April 06, 2020, 08:34:41 PM »

Why is it that enolates are more stable on ketones than aldehydes? For instance, the below drawing is incorrect and the double bond should occur by the other oxygen.

Think about the corresponding double bonds.
Which one is more stable and why?

So it's because aldehydes are more reactive because they have an unprotected hydrogen?

Rather because ketones have more stable enol forms as containing a more substituted and consequently, a more stable double bond.
