The molecular mass of acetone, (CH_3)_2 CO, is 58, while that of urea, (NH_2)_2 CO, is very close to that at 60. The molecular mass difference is insignificant for this problem. One of these is a solid and the other a liquid. Decide which one is expected to be the solid and which liquid. Explain your choice using intermolecular forces. Identify all intermolecular forces. The molecular masses of the following five molecules are all between 100-104, and will not be a factor in your answers to the questions. Do not look up data; answer the questions using basic principles of intermolecular force strength. For the last three questions, identify all intermolecular forces. a. b. c. d. e. CH_3 CH_2 CH_2 CH_2 CH_2 CH_2 CH_3 Arrange these molecules in the expected order of decreasing vapor pressure. (lowest last) Which of these molecules is expected to have the lowest boiling point? Explain on the basis of intermolecular forces not vapor pressure.
