Title: Grignard Reaction Questions
Post by: jemexpress on June 11, 2021, 03:23:25 PM

Hello!

I have an organic chemistry lab next week and I’m supposed to do a liquid liquid extraction that I have to “design” myself. The reaction is as follows:

Magnesium + Bromobenzene (with di ethyl ether, HCl, and dry ice as catalysts/intermediates). After all of this is mixed it’s to be added to a seperatory funnel.

My question is — how am I supposed to know what’s in the organic layer and what’s in the aqueous layer? I’m supposed to be isolating the benzoic acid in the mixture. What layer would that be in?

Which solvent is benzoic acid more soluble in, water or diethyl ether?
