Reaction of acyl chloride with excess Grignard reagent I have a reaction to which I must find the majority organic product.

I think I found the correct product but the fact that the reaction takes two moles of propylmagnesiumbromide confuses me a bit. I added an image of the product I think would be the result.

I would like to know if I found the right product, and if the two moles of propylmagnesiumbromide means that there is a second part to this reaction.
The following paragraph from chem.libretext.org1 sums up the answer to your question:

Acid chlorides react with Grignard reagents to produce tertiary alcohols. Two equivalents of the Grignard reagent are needed because the first equivalent reacts to form a ketone which then reacts with the second equivalent. Because of the high reactivity of the Grigard reagent, the reaction can NOT be stopped at the ketone.


Coming to your specific case the reaction would proceed with the following mechanism:
