Questions : 1. In Graph 1, the higher boiling points of low molecular weight hydrocarbons violate the general trend. "molecular size is related to molar mass," in which lower molecular weight molecules boil at lower temperatures than higher molecular weight molecules. State the reason why there is a violation in the general trend observed for hydrocarbons. (Hint: Make molecules of these substances and consider molecular size). Hydrocarbons have more atoms so, even though they have a lower molar mass, they have more surface area allowing for stronger London Dispersion forces. This makes the physical attraction stronger than that of halogens and noble gases. 2. In Graph 2, the high boiling point of H 2 O violates the general trend in which a small molecule boils at lower temperature than a large molecule that is otherwise similar. State why H 2 O is higher boiling than methanol, CH 3 OH. The reason water’s boiling point is higher than methanols is because of hydrogen bonding. The slight positive charge on the hydrogens
