please provide an equation for the reaction of the aqueous layer with Hdl.
The following experiment was done:
add 1g of 1:1 mixture of benzoic acid and naphthalene. add 30 ml of
dichloromethane to dissolve. Add solution to a separatory funnel.
Add 15ml of NaOH, shake and separate the two layers.
with the aqueous layer, containing NaOH, combine 6M HCl until you have reached a pH of 2. ice to speed up the production of crystals.

The alcohol could easily be converted to a tosylate, a good
leaving group, and a conventional substitution reaction could have
been performed instead of the nucleophilic aromatic substitution
(NAS) reaction. Why was the NAS reaction the preferred method?

Extraction of solids: Experiment outlined below
Draw a “roadmap” of the experiment, containing chemical
structures and “layers” (organic and aqueous). This should contain
the individual reactions occurring in each step, and show which
layer the various components are present. Make sure you think about
whether the acetaminophen, caffeine and aspirin are neutral,
protonated or deprotonated.

With stirring, add to this mixture 30 mL of 1.0 M potassium tert-butoxide (caustic alkali!) in tert-butyl alcohol using a syringe. Using a simple distillation apparatus, distill the mixture slowly, with...

Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substancesthat have varying solubility properties. Typically an aqueous solution can be extracted with anorganic solvent to isolate a compound or vice-versa. The specialized piece of glassware that isemployed for these types of separations is called a separatory funnel.In this experiment a mixture of benzoic acid and naphthalene will be purified using liquid-liquidextraction, more specifically an acid-base extraction. Since both compounds are soluble inethyl acetate (an...
