Cycle A- Practice Set (Solubility Properties)

• At least a paragraph reflection that describes the types of problems you really understood and why.  Give at least one example.
• I understand how the “like attracts like” concept works and how to distinguish which Lewis structures are polar and which are nonpolar. Problems dealing with which molecule would be most similar to H2O or any other polar/nonpolar molecule are simple. The conditions behind how a molecule is polar/nonpolar makes sense to me and are fairly easy to remember. I also understand the single/double that the molecules can make and why some are stronger/weaker than others.
• At least a paragraph reflection that describes the types of problems you struggled with and why. Give at least one example.
• I’m having some problems with distinguishing which molecule has the greater polarity (methanol or acetone). I’m also having a bit of trouble with problems having to do with isomers. I still get a bit confused when it comes to anions with charges since it changes the Lewis structure.
• At least one picture of something you did in class during the week with a description of the picture.
• This picture shows the results of a lab our group did in class of hexane being mixed with water. The hexane doesn’t mix with the water since one is polar(water) while the other is nonpolar(hexane).
