This experiment was based on Aldol-dehydration reaction using
unknown aldehydes and ketones. We carried out an aldol condensation
between an unknown aldehyde and an unknown ketone. Here are the
list of possible unknown aldehydes and ketones that were used.
Here is the NMR of the final product. Please predict the
structure given the melting point is 163 degrees Celsius.
