Carboxylic acids

• What is the functional group of carboxylic acids?

  1. o-o-h
• What do the names of carboxylic acids end with?

  anoic acid
• What is the name of the carboxylic acid with three carbons?

  Propanoic acid
• What are the names of the first four carboxylic acids?

  Methanoic acid, Ethanoic acid, Propanoic acid, Butanoic acid
• How should the formulas of carboxylic acids be written?

  The c-o-h groups should always be put together at the end
• What type of acids are carboxylic acids?

  They are weak acids
• What does it mean that carboxylic acids do not fully ionize?

  It means that their molecules do not all release their hydrogen ions
• How is the ionization of carboxylic acids represented in equations?

  With an equilibrium arrow between the full acid and the ionized version
• What do the negative ions formed from carboxylic acids end with?

  anoate
• What does propanoic acid ionize into?

  A propanoate ion and a hydrogen ion
• What products are formed when a carboxylic acid reacts with a metal carbonate?

  A salt, water, and carbon dioxide
• What would be the products of reacting ethanoic acid with potassium carbonate?

  Potassium ethanoate, water, and carbon dioxide
• How are carboxylic acids made from alcohols?

  By oxidizing the alcohol using an oxidizing agent
• What is the name of the carboxylic acid produced from butanol?

  Butanoic acid
• What happens to the number of carbons when butanol is oxidized to form butanoic acid?

  The number of carbons remains the same
• What are the key characteristics of carboxylic acids?

  • They are a homologous series of organic compounds.
  • They have the functional group c-o-o-h.
  • Their names end in "anoic acid."
  • They are weak acids that do not fully ionize.
  • They form negative ions ending in "anoate."
• What is the general reaction of carboxylic acids with metal carbonates?

  • React with metal carbonates to produce:
  • A salt
  • Water
  • Carbon dioxide
• How are carboxylic acids synthesized from alcohols?

  • Oxidation of alcohols using an oxidizing agent.
  • Example: Butanol oxidized to butanoic acid.
