Predicting whether molecules are polar or nonpolar.
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)
Decide whether each molecule or polyatomic ion is polar or nonpolar. If the molecule or polyatomic ion is polar, write the chemical symbol of the atom closest to the negative side. For example, if the molecule were HCl and you decided the hydrogen atom was closest to the negative side of the molecule, you'd enter "H" in the last column of the table.

Question 34 of 50 > 0.5 / 1 View POIICIES Show Attempt History Current Attempt in Progress Mercury, water, and bromine are liquids at standard temperature. Their molar entropies are in the sequence H2O < Hg < Br2. Incorrect. Using molecular properties, explain why bromine is more disordered than mercury. Select those that apply. Bromine is diatomic. Mercury is monoatomic. Diatomics are more ordered than monoatomics. Water has strong hydrogen bonding interactions. O Hydrogen-bonded substances are less ordered than substances without hydrogen-bonds.
