Why are ducks waterproof? It’s because they produce copious amounts of oils from their uropygial glands and spread it across their feathers. In this exercise, we’ll be investigating the molecular structure of one of these preen oils to determine how it keeps ducks dry. Q3. Preen oil protects the duck’s feathers, as it will not dissolve in water. Identify the strongest intermolecular interactions preen oil can have. Identify the strongest intermolecular interactions the following solvents have. Preen oil 3.jpg (image attached) Which of these solvents would be capable of dissolving the preen oil off of a duck’s feathers? Q4. The preen oil sticks to itself and the duck as it is spread along the feathers. What is happening down on the molecular level that causes an attraction between the different molecules of preen oil?

The preen oil sticks to itself and the duck as it is spread along the feathers. What is happening down on the molecular level that causes an attraction between the different molecules of preen oil? Make sure to explain specifically what phenomenon causes the attraction between the different preen oil molecules. It’s not enough to say “They are both nonpolar molecules.”
