D) ceramic Secondary and tertiary alcohols undergo elimination reactions when heated in the presence of a strong acid, such as sulfuric acid. I know the 3D VSEPR shapes, so am I supposed to come up with that and then see which is nonpolar or polar? Thus, we see molecules such as PH3, which do not participate in hydrogen bonding. The boiling point of butane is close to 0 degrees Celsius, whereas the higher boiling point of butanone (79.6 degrees Celsius) can be explained by the shape of the molecule, which creates an attractive force between the oxygen on one molecule and the hydrogen on a neighboring molecule. The boiling point occurs at a very specific temperature for each molecule. We could have used the trend of lower atomic (molar) mass having a lower boiling point on Q1 and Q2, only if it states that answers (C) and (D) are n-$\ce{C5H12}$ and n-$\ce{C4H10}$, respectively (or i-$\ce{C5H12}$ and i-$\ce{C4H10}$, respectively).
