2. Although aldehydes and ketones undergo almost the exact same reactions, aldehydes are generally more reactive than
ketones. As an example, the pKa of the circled hydrogen on the aldehyde below is 16, while the pka of the circled
hydrogen of the ketone below is 19. (i) Explain why aldehydes are (generally) more reactive and more acidic that
ketones. As part of your explanation, be sure to (ii) include a judiciously chosen, fully labeled diagram.
pka = 16
pka = 19
