**Tue Dec 05, 2017 2:58 pm**Question 12.49 on the homework says:

Which is the stronger base, the hypobromite ion, BrO- , or morphine, C17H19O3N? Justify your answer.

The answer to the question is that the stronger base is the hypobromite ion.

I understand that for oxoacids, the more oxygen atoms there are in a compound, the stronger it is as an acid. Would it be correct to conclude that the hypobromite ion is a stronger base because there are less oxygen atoms? Or is there a better way to approach this question conceptually to determine which of the two is a stronger base? The solution manual provides the values of the pKb of both, but how exactly are we expected to figure that out if no numbers are given in the question? Is that a value given to us/a value we must memorize?

Is there a way to answer the question just by looking at the formula?
