Amides

Structure

  • derivatives of carboxylic acids with an amide group

  • -CONH2

Nomenclature

  • named from the corresponding acid

    • remove oic acid and add amide)

    • CH2CH3CONH2 = propanamide

amide nomenclature

Hydrolysis

  • general

    • CH3CONH2 + H2O —> CH3COOH + NH3

  • acidic solution

    • CH3CONH2 + H2O + HCl —> CH3COOH + NH4Cl

  • alkaline solution

    • CH3CONH2 + NaOH —> CH3COONa + NH3

Identification

  • warming an amide with dilute sodium hydroxide solution

  • testing for the evolution of ammonia using moist red litmus paper
