Carbonyl compounds

• What is the carbonyl functional group?

  C=O
• What reaction do carbonyl compounds undergo?

  Nucleophilic addition reactions
• Reducing agent

  Sodium borohydride - NaBH4
• Why does Sodium Borohydride act as a reducing agent

  NaBH4 dissociates in water to form Na+ and BH4- which produces a H- ion as an electrophile
• Reducing agent symbol

  [H]
• Where do the hydrogen ions come from

  H+ from water

  H- from reducing agent
• Conditons for Electrophilic addition (reduction of an alcohol)

  NaBh4 and H2O
