Experiment: Passerini Reaction t-butyl isocyanide + benzaldehyde + benzoic acid were reacted to form 2-(tert-butylamino)-2-oxo-1-phenylethyl benzoate. Water was used as the medium for the reaction, allowing for faster reaction times and higher yields (is an example of green chemistry technique, since no organic solvents are involved in the synthesis of the reaction itself). QUESTIONS: 1. Consider the molecular structure of the Passerini Product. In light of the composition of the compound, explain the observations you made regarding its behavior upon...

Please help with pre-lab questions.
Pre-Lab Questions: 1. A sample of 2-butanol has a specific rotation of +3.25. Determine the optical purity (%ee) and percent composition of this sample (see Mohrig section 17.4). The specific rotation of pure (+)-2-butanol is +13.0°. 2. The equation for the formation of the diastereomeric salts is shown in the background information (performed in Part A of the procedure). Write this chemical equation in your notebook, then ALSO write a balanced equation for the formation...

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...

Step 1. Preparation and Recrystallization of a Diastereomeric Salt - Synthesis of (R,R)-1,2-Diammoniumcyclohexane mono-(+)-tartrate: In a 150 ml beaker, L-(+)-Tartaric acid (7.5 g, 0.05 mol) is dissolved in 25 mL of distilled water. The solution is stirred as 11.4 g (12.2 mL, 0.10 mol) of 1,2-diaminocyclohexane is added carefully in one portion. (The addition of the diamine is exothermic.) A slurry is formed initially but complete dissolution is observed once addition...
