Based on the information provided in manual and during the lecture, design the procedure for reduction of 2.5 mmol of vanillin by using sodium borohydride. Propose solvent, amount of reagents and solvent to be used, temperature in which reaction should be performed, time of reaction, and method of separation and purification of the product. Your procedure should be as detailed as procedures in the manual, so that any your colleague should be able to perform an experiment based on your description. Please show calculations.

hi, please help me with number 7. thank you
EXPERIMENT SEVEN SODIUM BOROHYDRIDE REDUCTION OF ACETOPHENONE HOCH, DISCUSSION The reduction of an aldehyde or ketone with sodium borohydride is straight forward and usually affords a high yield of the alcohol. The usual procedure (and the one employed in this experiment) involves dissolving the borohydride in 95% ethanol and adding the carbonyl compound to this solution. To ensure complete reaction, an excess of sodium borohydride is used. The reaction between sodium...

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...

Multistep Synthesis: Synthesis of Amine (Organic Chemistry
Lab)
Question
1. Explain each step of reaction mechanism. (How does it
work?)
2. Discuss reason for reaction sequence. (Why must one reaction
occur before another?)
3. Explain how IR supports the major product.
Experiment Procedure
Imine Formation:
Weigh a 20 mL beaker and then add 380 mg of ortho-vanillin and
268 mg of para-toluidine. Care should be taken to add equivalent
molar amounts of the two reactants.
Observe the mixture and record...

molecules assigned to you. In each case the organic
starting material (what you have to work backwards toward) depends
upon the target. For the structure given above (structure on left),
the starting material is either malonic ester or acetoacetic ester
and any halide. For the structure given above (structure on right),
the starting material is any...
