Answer:
-) Acid-base reaction
-) Carboxylic acid, alcohol, alkene and ketone
Explanation:
For the reaction between acetic acid and triethylamine, we will have an acid-base reaction. Therefore a salt would be produced in this case an "ammonium quaternary salt". Also, we have to remember that on this reaction the acid is the acetic acid and the base is the triethylamine. See figure 1
For the second question, we have to check the structure of Prostaglandin E1 in which we have the functional groups:
1) Carboxylic acid
2) Alcohol
3) Alkene
4) Ketone
See figure 2.
I hope it helps!
