Categorizing reactivity by oxidation state Major concepts In organic chemistry, it is useful to group functional groups into oxidation states: alkane, alcohol, ketone, carboxylic acid, carbon dioxide. Reduction can be recognized by the net gain of C-H bonds or loss of C-Q bonds; oxidation can be recognized as the net gain of C-Q bonds or loss of C-H bonds. Vocabulary Oxidation state Redox reaction Students should be able to: Be able to group functional groups into distinct oxidation states Know the type of mechanism(s) that are active within each oxidation state Daily Problems 1. In the chart below, fill in the names of each redox category, starting with the most reduced on the left. Then fill in the following functional groups in each category: Alcohol, phosphate monoester, thioester, alkene, carboxylic acid, alkane, enol, acetal, amine, alkyl halide, alkyne, ketone, aldehyde, ester, amide, imine 2. Fit each of the following mechanisms into redox categories listed in problem #1: electrophilic addition, nucleophilic substitution, elimination, nucleophilic addition, nucleophilic acyl substitution 3. Organize the following molecules into groups according to oxidation state, starting with the most reduced group on the left.
