Aldehyde Reactions: Carboxylic Acid Formation from Aldehyde using Silver
Carboxylic acids can be formed from aldehydes using silver oxide (Ag2O):
Silver oxide is typically the reagent presented however, it could be represented as Ag+ or AgNO3. Alcohols will not oxidize with Ag2O making this reacting helpful in synthesis reactions where you have to account for an alcohol functional group:
No reaction mechanism is presented for this reaction as it is very convoluted and never taught during Organic Chemistry 1 or Organic Chemistry 2.
