Lesson 4: Macromolecules and Reaction Types

Reaction Types

• Neutralization
  : acid + base → salt + H₂O

• Condensation (Dehydration Synthesis)
  : remove H₂O (OH + H) to join molecules (anabolic)

• Hydrolysis
  : uses H₂O (OH + H) to break down larger molecules into smaller ones

• Redox
  : reactions that involve the transfer of e^- (gain and loss)

  • Loss Of Electrons (LEO)

  • Gain Of Electrons (GER)

    • “LEO the lion says GER”

  • any element by itself has an oxidation # of 0

  • elements in a compound have an ON depending on the formula and/or periodic table (# of valence e^-)

  • oxidized element = reducing agent

  • reduced element = oxidized agent
