  1. Organic Reactions Group Investigation Amides Tiffany, Jasdeep, Yosola, and Fatima

  2. RULES/LAWS • Amides are involved in the following reactions : • Condensation • - where a carboxylic acid reacts with a amine to produce an amide and water • Hydrolysis • - Where water reacts with an amide, producing a carboxylic acid and an amine • Dehydration • Reduction

  3. Structural Drawings - Dehydration of Amides - Amide Reduction

  4. - Condensation Reaction - Hydrolysis Reaction • Water molecule reacts with amide • OH attached to carbon with double-bonded oxygen • Hydrogen bonds with nitrogen • Carboxylic acid and amine are produced • OH from carboxylic acid and H from amine is removed to form water molecule • Carbon bonds with nitrogen to form amide

  5. Practical and Industrial Uses • Amides are used widely in industry. • Amides are found in the plastic and rubber industry, paper industry, water and sewage treatment and colour, in crayons, pencils and inks.

  6. Environmental Impact • Amides are all found in rubber, plastic and oils, all of which are hard to break down and disintegrate because: • It takes over a 100 years to break amide bonds under conditions of mild-neutral pH • Amines are usually a product of broken down amide bonds, and are highly toxic to the environment • In landfills, when amides disintegrate the amines that are formed can travel by water from rain into surrounding areas • Amines can also be absorbed by the ground and contaminate groundwater

  7. Concise Summary of Reactions • Condensation: - Carboxylic acid and amine react together to form amide and water molecule • Hydrolysis - Amide and water molecule react together to form carboxylic acid and amine • Reduction - Amides can be reduced by using LiAlH4 - Converts C=O to -CH2- by using substitution and addition • Dehydration - Primary amides can be converted to nitriles with a dehydrating reagent such as P2O5

  8. Interactive Quiz! Have you been paying attention? What are the four different types of reactions an amide can undergo? Condensation, hydrolysis, reduction, and dehydration It takes over ____ years to break amide bonds under mild neutral pH. 100 Phosphorus pentoxide 3. Conversion of amides to nitriles can be done by using ________________ as a reagent. 4. Name a use for amides. Paper and rubber industries, crayons, plastics, sewage and water treatment. 5. What happens during the hydrolysis of an amide? Water and an amide react to form carboxylic acid and amine.
