What are the namesof the product of the aldol-dehydration reaction with the given aldehydes (A) and ketones (K)?
1) A = tolualdehyde + K = 4-Me-cyclohexanone
2) A = tolualdehyde + K = cyloheptanone
3) A = anisaldehyde + K = acetone
4) A = anisaldehyde + K = 4-Me-cyclohexanone
5) A = anisaldehyde + K = cyloheptanone
6) A = cinnamaldehyde + K = acetone
7) A = 2-furaldehyde + K = cyclohexanone

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.
The analysis of the 1H NMR spectrum should include a detailed
assignment of each of the NMR resonances to the protons...
