4. (3 pts) You accidentally add too little hydrazine (H2NNH2, 0.25 mL) to the reaction test tube and the solution is already heating to almost 100 °C. How would you correct this mistake? If left unfixed, what would you expect the effect on the yield to be? 5. (3 pts) You accidentally added half the amount of 3-nitrophthalic acid to the reaction. You have already started filtering the first product. How would you correct this mistake? If left unfixed, what...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...

Q: Calculate the expected mass of both methyl salicylate and
aspirin assuming 100% yield.
EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...
