For each reaction, decide whether the reaction is a redox reaction, acid-base reaction, electrophile- nucleophile, or something else. One can begin to identify the type of reaction by looking to see if oxidation numbers of atoms that take part in the reaction change during the reaction. You will need to draw out the structures. a. If the reaction is considered an acid- base reaction, draw out the full mechanism for the reaction. Be sure to indicate which compound is the acid, base, and conjugate acid and base (where possible). b. If the reaction is considered a redox reaction, be sure to indicate which species are oxidized and which are reduced. c. For every reaction you will need to justify your identification of the type of reaction.

This experiment is aldol condensation reaction. Complete the table
In a mixed aldol condensation with unknown aldehydes and ketones experiment, some aldol condensation reactions need to be heated for the dehydration step to occur. Explain why that was not necessary for the reactions carried out in this experiment? [Hint: what makes the product especially stable?]. This experiment used ethanol, acetic acid, sodium hydroxide, cyclohexanone and 4- methoxybenzaldehyde.
