Naming & Drawing Carboxylic Acids

• Carboxylic acids are not counted for methane acid
• Carboxylic acids


  Used in the chemical industry to make a substance called esters
• Ethanoic acid


  A commonly used carboxylic acid
• Vinegar


  Used in household cleaning products as it is a non-toxic acid so can be used safely in household situations
• Carboxylic acids


  Contain the carboxyl functional group
• Carboxyl functional group


  O==COOH
• Carboxylic acids


  1. OH
• Carboxylic acids


  • Methanoic
  • Ethanoic
  • Propanoic
  • Butanoic
• Carboxylic acids


  Miscible in water up to a certain size, thereafter their solubility decreases
• As carboxylic acids increase in size

  Their melting point and boiling point increase
• Reason for increasing MP/BP

  Due to the increasing strength of the intermolecular forces
• Number of C atoms

  • 1
  • 2
  • 3
