3. Structurally compare and contrast the compound responsible for the odor and flavor of pear(propyl acetate or propyl ethanoate) to the compound responsible for the odor and flavor ofblackberries (propyl hexanoate.) How are they similar? How are they different? Draw structuresto show how each of these compounds is formed from its "parent" molecules. Name all thecompounds involved.4.
