Topics 6
- Nomenclature and structure of the carbonyl group; physical properties
- Preparation from alcohols, alkenes (ozonolysis), alkynes (hydration), acid chlorides (Rosenmund, dialkyl cadmium), calcium salts of acids, nitriles (Stephen, Grignard) and esters
- Nucleophilic addition with mechanism: HCN, NaHSO3, Grignard reagents, ammonia and its derivatives
- Oxidation and the iodoform reaction; reduction to alcohols and alkanes (Clemmensen, Wolff-Kishner, red P and HI)
- Base-catalysed reactions with mechanism: aldol, cross aldol and Cannizzaro reactions; reactivity of alpha-hydrogen
- Tests distinguishing aldehydes from ketones and formaldehyde from acetaldehyde; uses
