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. Q.5 - Preen oil is actually a complicated mixture of many different organic compounds, such as the structure seen previously.. Ornithologists have determined that birds often use preen oil compounds for scent recognition. Below, several different chemicals isolated from preen oil are shown, along with their vapor pressures at room temperature. p-cymene has the highest vapor pressure, meaning it is the most easily evaporated compound of the three listed. Explain why p-cymene has a higher vapor pressure at room temperature compared to the other compounds. Make sure to explain what holds the p-cymene in the sample. (Image attached)

11. Suppose an obligate aerobic chemolithotroph was able to use any of the potential energy sources listed in the table below as a source of electrons. Which energy source (i.e., electron donor: I want the molecule not the redox couple) would provide the greatest amount of free energy? (Note: all the redox couples listed are two electron transfers). Explain your answer – MATH works well for this. Redox Couple Po -0.42 2H H2 +0.42 NO, NO, %0H0 +0.82 s'H,S so, s0," -0.28 2- 2- +0.02 12. Consider a redox reaction involving the redox couples S/H2S and NO3/NO, in the above table. (a) Which molecule (I want the molecule, not the redox couple) would be the electron acceptor? Why? Use the table above to help answer this question. (b) (Suppose a chemoorganotroph could acquire electrons from H2 using either oxygen or nitrate (NO3) as the terminal electron acceptor. Per two electrons transferred, determine if the use of nitrate or oxygen will yield more energy? You must show how you arrived at…
