For a given type of compound (alkane, alcohol, amine, or ether): a. How does the boiling point change as the molar mass of the compound increases? b. Do the intermolecular forces (attractions between) molecules Increase or decrease as the molar mass increases? Discuss with your team and explain your choice. 11. Work with your team to choose an alkane, an alcohol, an amine, and an ether with roughly the same molar mass (within 5 g/lmol). Rank these compounds in terms of relative boliling points. 12. Repeat CTQ 11 with another set of four compounds. 13. Does polarity in molecules tend to Increase or decrease the strength of intermolecular interactions? Write a team consensus explanation of your reasoning. 14. Based on relative boiling points, write the numbers from 1 to 4 under the functional group names below, with the number 1 being the group with the most intermolecular attractions, and 4 being the least alkane alcohol ether a mine 15. For each functional group below, circle each type of b cotained in the molecule. You may refer to Model 2 Type of bond C-0 C-0 C-0 C-0 Functional group C-H C-H C-H C-H N-H N-H N-H N-H alkane O-H ether 0-H 16. Based on your answers to CTQs 14 and 15, which two types of bonds are present only in molecules containing the two functional groups with the strongest intermolecular 23
