  1. Amines By: David Eastwood & Morgan Gentes

  2. Structure Amines are a derivative of ammonia where organic groups replace one or more of the Hydrogen's. NH3 RNH2 R2NH R2N Primary Secondary Tertiary Amine Amine Amine

  3. Ammonia VS. Amine The Chemistry of amines and ammonia are similar. The most obvious feature is their basicity (being able to accept a proton) which comes from the unshared pair of electrons. Compare acceptance of a proton in an Amine and an ammonia. H H R\ | R\ | R- N : + H R – N – H R- N : + H R – N – H R/ | R/ | R R

  4. Naming Amines When naming Amines you sue the Prefix “amino” and the suffix “-amine” Lower amines Higher amines have are named with the prefix amino as the suffix a functional group. -amine. NH2 H\ H | N – C – H CH – CH – CH – CH – CH H/ H Methylamine 2-Aminopentane

  5. ethyl amine or ethanamine

  6. cyclobutyl amine or cyclobutanamine

  7. N-ethylethyl amine or N-ethylethanamine or diethyl amine

  8. 3-amino-2,6-dimethyl-4-propyloctane

  9. Prepared Amines Amines can be prepared by a substitution process called Alkylation, where an alkyl group becomes bonded to a Nitrogen. http://www.chem.ucalgary.ca/courses/351/Carey5th/Ch22/ch22-3-1.html
