We have seen that molar mass and molecular structure influence the boiling point. We can see these two factors at work in the boiling points of the Group 6A hydrides shown in the graph.
In order to disentangle the effects of molar mass and molecular structure on boiling point, consider the data in the table.
Use the information in the graph and the table to answer the questions.
a. Does molar mass alone correlate with the trend in the boiling points for the Group 6A hydrides?
b. Which boiling points in the graph correlate with polarizability? Which type of intermolecular force correlates with polarizability?
c. Use the data in the table to explain the anomalously high boiling point of water.
