Hi, so I'm wondering if I did this substitution reaction right. The only thing that the book did differently is that, it didn't transfer the proton to the other oxygen. I'm wondering is the mechanism that I wrote is still valid or not? It's question 7a by the way, I've attached the question and my answer. Any input would be greatly appreciated

You are making an acid anhydride. After you hydrolysed the acid chloride to the acid what do you think happens then?

2 of the intermediates will come together, the C=O from 1 will attack the ketone on the other to form the product, right?

the 2 electrons from the C=O pi bond I mean

They sound like long lost lovers
The compounds are not ketones, one is an carboxylic acid chloride, the other is a carboxylic acid. If water can attack (hydrolyse) the acid chloride what do you think the carboxylic acid can do?
