Oxidation-Reduction Reactions in Organic Chemistry An oxidation reaction often can be recognized by either an increase in oxygen content or a decrease in hydrogen content. Similarly, a reduction reaction usually involves the opposite changes. RCOH O = carboxylic acid reduction oxidation RC-H H OH alcohol [H] [O] The symbol [H] means reduction and the symbol [O] means oxidation.

Formal Oxidation States A formal oxidation state may be assigned to a carbon as follows: • A bond to another carbon is 0 (zero). • A bond to H (or anything less electronegative) is -1. • A bond to a more electronegative atom (O, N, halogen) is +1. Example: For the sequence The formal oxidation states at C are:

Alcohols by Reduction of Carbonyl Compounds Primary and secondary alcohols may be prepared by the reduction of several carbonyl functional groups: R-C-H O = aldehyde [H] R-C-R' O [H] ketone R-C-OH O [H] carboxylic acid R-C-OR' O [H] ester
