(a) Which is the stronger acid:

---

(b) Which is the stronger base:

Sample Solution (a) The ionizable proton is bonded to N in and to O in

Nitrogen and oxygen are in the same row of the periodic table, so their relative electronegatiy ities are the determining factor. Oxygen is more electronegative than nitrogen; therefore is a stronger acid than
