Nucleophilic Addition: Aldehydes vs Ketones | 19.3 Organic Chemistry

In this lesson Chad provides an introduction to the general mechanism and result of Nucleophilic Addition to aldehydes and ketones. He also explains the reasons behind the general trend in the reactivity of aldehydes and ketones: formaldehyde more reactive than aldehydes more reactive than ketones.

Hydration of Aldehydes and Ketones
The lesson concludes with the hydration of aldehydes and ketones which involves the nucleophilic addition of water and the resulting hydrates which are present in equilibrium in aqueous solutions of aldehydes and ketones.

Finally, Chad presents the hydration of aldehydes and ketones reaction including both the base-catalyzed mechanism and the acid-catalyzed mechanism.
