Which of the following: benzaldehyde, acetone, NaOH, and
dibenzalacetone is water soluble? Why?
You refined the crude product in the simulated experiment by
recrystallization without first verifying its
structure. Briefly explain.
Compare the melting points of dibenzalacetone in the lab and in
the literature. What does this imply?
What further characterization procedures should you employ to
confirm the product's structure?
What happens if the solution for recrystallization cools down
too quickly?
List down, arrange and organize the procedures in the experiment
according to the four (4) key steps in carrying out an organic
synthesis:
a. Set-up/Synthesis
b. Work-up to isolate the product
c. Purification to remove impurities
d. Characterization to identify the product
