In problem 6C.17 from the textbook, it asks "which is the stronger base, the hypobromite ion BrO- or morphine C17H19O3N." Why is the hypobromite ion the stronger base?

I believe its because there is a negative charge on the BrO- molecule.

For this question, they specifically wanted you to look at the provided table, understanding that if pKb is lower then the substance is a stronger base. The given values are pretty close, so I don't think they'll give us a problem like that without giving us the K value. For the questions dealing with periodic trends in order to determine acid strength, you'll notice that the two substances parallel each other in some way, with one key difference.
