Carboxylic acids

• What happens when carboxylic acids dissolve in water?

  They partially ionize to produce ions
• What is the functional group of carboxylic acids?

  Carboxyl group
• Why are carboxylic acids considered weak acids?

  They only partially ionize in aqueous solution
• What is the displayed formula for ethanoic acid?

  CH₃COOH
• What is produced when ethanoic acid reacts with sodium carbonate?

  Sodium ethanoate, carbon dioxide, and water
• What is formed when carboxylic acids react with alcohols?

  An ester and water
• What is the name of the ester formed from ethanoic acid and ethanol?

  Ethy ethanoate
• What catalyst is required for the reaction between carboxylic acids and alcohols?

  Sulfuric acid
• How does the reaction of carboxylic acids with metal carbonates differ from their reaction with alcohols?

  Metal carbonates produce carbon dioxide, alcohols produce esters
• What are the key reactions of carboxylic acids?

  • Reaction with metal carbonates:
  • Produces salt, carbon dioxide, and water
  • Reaction with alcohols:
  • Produces ester and water
• What are the first four carboxylic acids?

  1. Methanoic acid (HCOOH)
  2. Ethanoic acid (CH₃COOH)
  3. Propanoic acid (C₂H₅COOH)
  4. Butanoic acid (C₃H₇COOH)
• What is the significance of the carboxylic acid functional group?

  • Defines the properties of carboxylic acids
  • Responsible for their acidic behavior
• What is the difference between strong acids and carboxylic acids in terms of pH?

  • Carboxylic acids have a higher pH than strong acids
  • Strong acids fully ionize, carboxylic acids partially ionize
