Aldehyde Disproportionation A Structure Proof Problem

The reaction mixture in this experiment contains 4-chlorobenzaldehyde, methanol, and aqueous potassium hydroxide. A reaction occurs that produces two organic compounds. Compound 1 and Compound 2. Both are solids at room temperature. Your task is to isolate, purify, and identify both compounds. A specific procedure is given for preparing the compounds, but you will need to work out the procedures for most other parts of this experiment. 

If the work on this experiment is done in pairs, work closely together as a team, dividing up the work equitably. A logical division of labor is for one student to work on Compound 1 and the other to work on Compound 2. Whether you work in pairs or not, you will need to plan your work carefully before coming to the laboratory, to make efficient use of class time. 

Dispose of all filtrates into the container designated for halogenated organic 

This procedure should produce enough of each compound to complete the experiment however, in some cases it may be necessary to run the reaction a second time. Although this experiment can be done individually, it works out especially well for two students to work together. 

Be sure there is no acetone present on any of the glassware. Acteone will interfere with the desired reaction.
