Textbook Question
Chapter 2.9, Problem 38P
Using the table of pKa values given in Appendix I, answer the following:
- a. Which is the most acidic organic compound in the table?
- b. Which is the least acidic organic compound in the table?
- c. Which is the most acidic
carboxylic acid in the table? - d. Which is more electronegative: an sp3 oxygen or an sp2 oxygen? (Hint: Pick a compound in Appendix I with a hydrogen attached to an sp2 oxygen and one with a hydrogen attached to an sp3 oxygen and compare their pKa values.)
- e. Which compounds demons that the relative electronegativities of a hybridized nitrogen atom are sp > sp2 > sp3?
