Organic chemistry: Aldehyde/ketone nomenclature problems. Spectroscopy problems. Hydration (nucleophilic addition of water to aldehydes and ketones to form geminal diols). Reactivity of aldehydes and ketones. Effects of acid or base on reactivity. Mass spectrometry of aldehydes and ketones; McLafferty rearrangement. Nucleophilic addition of thiols to aldehydes and ketones to form thioacetals; desulfurization of thioacetals with Raney nickel.
