Question

How do you prepare the benzoic acid from Grignard reagent?

Answer 1

$\mathfrak{\huge{\orange{\underline{\underline{Answer :}}}}}$

Benzoic acid synthesis:

1. Carboxylate salt made combining Grignard reagent and dry ice in ether solvent.
2. Extract the ether phase with base (5% NaOH): Product converted to carboxylate salt and transferred to aqueous layer (top or bottom layer?)
3. Acidification causes the carboxylic acid to precipitate out of solution.
