Chapter 12 #39 asks:

12.39 Using data in Tables 12.1 and 12.2, place the following acids in order of increasing strength: HNO2, HClO2, NH3OH, (CH3)2NH2

Considering we won't have these tables to use during the exam, are we expected to be able to place acids in order of strength? If so, could someone explain their reasoning on how to do this question?

You can expect to find a problem similar to this in that you rank species in terms of acidity. The reasoning would be more clear, and is related to the factors Dr. Lavelle discussed in class like resonance stabilization of the conjugate base.

For parts c and d, the molecules are actually +NH3OH and (CH3)2NH2+, so how would we find these values in the table that the problem tells us to look at? Are we supposed to set up some sort of equation from the conjugate bases that we do see in the table?
