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.

Please help with question 3. Thank you!
Disposal of waste: When necessary, all organic waste must be disposed into the organic waste container, all aqueous waste to the aqueous waste container and all solid waste to the solid waste container. Nothing is disposed in the sink or trash can. Synthesis of acetanilide In a dry small conical vial, dissolve 300 mg (or 30 drops) of freshly distilled aniline in 1.0 mL of 1.0 M hydrochloric acid. Swirl the mixture to...

Question to answer from the lab: What aspect(s) of the approach taken is/are NOT especially green? What changes might be made to make the overall process greener? The Lab Experiment Summary Polyethylene glycols such as PEG-400 are currently of great interest to organic chemists, since their application as reaction solvents is very intriguing (1). PEG-400 is non-volatile and nonflammable in nature, and also possesses important properties such as recyclability, ease of work-up, thermal stability and economical cost. In addition, the...

Let's assume you have a mixture of equal parts benzoic acid, sand and toluene that are intimately mixed together (the crude material is a mixture of solid and liquid). Propose a procedure to separate these three components using any of the chemicals commonly available (you've used all of the "common" chemicals in the lab by now) in the organic chemistry teaching laboratories and observing the typical limitations with the instruments and techniques (such as not being able to distill or...

Based on the Wittig Reaction exp. below, please answer a) and
b). In b) you can disregard the part about the IR, just please
interpret and assign protons, shift values, which protons are for
which groups, etc on the HNMR. The % yield was 34%, and MP was
lower than expected (to assist with answering part a). This should
be all the information you need to answer the question.
