Document Summary
Pre lab 3 homework (35 pts total: read through the experimental for lab 3 in your manual and write out the procedure into your lab notebook, leaving room for observations etc. Benzophenone is the more polar compound due to the presence of an oxygen atom. The biphenyl molecule contains only carbon and hydrogen bonds, which are all considered to be nonpolar. However, benzophenone has an oxygen atom between its two carbon rings. The molecule still remains symmetrical, so this molecule would not be very polar but would certainly behave more polar than biphenyl. (c) which compound would you expect to interact less with a polar stationary phase? (2 pt) The biphenyl would be expected to interact less with a polar stationary phase due to the fact that it is a nonpolar molecule. This would cause it to not react very strongly with a polar substance.
