How can we complete questions 2-4 with the molecule?
General Chemistry 1 3. Use the table to predict how the molecular surface area affects boiling point. Think about a sphere - it has the lowest surface area for the given volume. The closer the molecular shape to a sphere the lower the surface area. Pick two more molecules from the table with the similar MM's and similar IMFs but with different surface areas - to illustrate how the surface area affects bp. A molecule with a smaller surface area has. boiling point a) Draw structures for the two more molecules, name all molecules, and list the types of intermolecular forces that are present in each case. bp (1) Sketches: Names:_ IMFS: b) Justify this trend from the point of view of IMFs only. A. bp (2) OH 4. Now that you've looked at all three trends you are ready to compare boiling points! (a) List the following compounds in order of decreasing boiling points. B. OH C. D. (b) Justify your answer using the trends we just discussed. bp (3) OH E. bp () > bp (_) > bp (_____) > bp () > bp (______)

of gravity on boiling point. molecular formulas if possible or, at least, similar molar masses to exclude the strate how IMFS affect boiling point you should choose molecules that properties of the compounds in the set that you choose. For 1. Pick two more molecules from the table that help you illustrate the following trend: certain trend you need to make sure that there is The stronger the IMFs the higher the boiling point (a) Draw structures for the two molecules, name all molecules and list the types of IMFs that are present in each compound in the liquid stat. bp (1) bp (2) O Sketches: Butane Names: IMFS: DISQUSION Sketches: Names: IMFS: < Butaname Dipole-Dipole (b) Do you expect vapor pressure for these compounds (at the some common temperature at which all of them are in liquid state) to follow the same trend? Why or why not? 2.
