SUMMARY
This discussion centers on the extraction of benzoic acid and benzil using dichloromethane and sodium hydroxide. When sodium hydroxide is added to benzoic acid, it forms sodium benzoate, while benzil, being nonpolar, does not react with dichloromethane but dissolves in it. The extraction process allows for the separation of benzoic acid into the aqueous layer, leaving benzil in the organic layer without any chemical reaction occurring between benzil and dichloromethane.
