Hi, during the Grignard run with acid halide and ester, a H3O+ issued to protonate the O- but I thought the Grignard reagent was so basic that it cannot co-exist with any acid?
So if a question ask for an ester reacts with grignard reagent,should I give the ketone or the tertiary alcohol as my answer,or the question won't ask like that (like will state the grignard reagent in excess)?Thank you very much
Ketones are more reactive than esters, so it’s impossible to pause this cascade in the middle. In the case of acid chlorides, chlorides are more reactive than ketones, so it’s possible to set up the experiment in some cases in such a way as to just get the ketone but not with esters. Unless your instructor talks about those reactivity details, the assumption will always be that the Grignard reagent reacts with esters and chlorides twice.
I’ve actually had it in the to-do list for a little while by now and am planning to upload a video on Markovnikov’s rule soon. I do have individual videos on all reactions where it’s applicable though but a review of it is a good idea too.
@@GurlMega it is on the to-do list for this semester. I have a few more videos scheduled before it but the Diels-Alder is currently tentatively scheduled for the next week.

Please post the mechannism of the gringard when you get time! And also the true bond struture and picture of the Gringard reagent
OH MY GOD THANK YOU!!!
Hope this is what you were looking for.

Acidic work up is done after the reaction is completed.

Can you please make a video on markonikov and anti markonikov rule

@@VictortheOrganicChemistryTutor Would it also be possible to do a video about Diels-Alder reaction? Ty for your effort in making these great videos
