Conceptual Checkpoint 21.22 Draw a mechanism of the following process. That is, draw a mechanism showing conversion of the conjugated, cyclic enone into the acyclic dione: For the mechanism, draw the curved arrows as needed. Include lone pairs and charges in your answer. Do not draw out any hydrogen explicitly in your products. Do not use abbreviations such as Me or Ph.

Provided in the explanation segment

Explanation:

In this question, due to the complexity in actually drawing this manually. i have attached an image that shows how this reaction occurs.

The mechanism as can be seen in the question involves an attack  of  the hydroxide ion which results in the formation of the enolate ion.

From protonation which follows deprotonation, we can see that the molecules give an acyclic di-ketone which is the desrired product.

i hope this solution was helpful.

Cheers i hope this helps!!!

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
