Presentation Transcript

  1. Esters (p. 49) • Organic compound formed by the condensation reaction of a carboxylic acid and an alcohol. • O O R-C-OH + R-OH R-C-O-R’ + H2O (ester)

  2. Esters (p. 49) O R-C-O-R’ • Naming: • Parent chain “R” (including the C bonded to the oxygens) • Name the parent as an alkane • Take off the “e”. • Add –oate • Branches • Identify alkyl group, R’ • Add alkyl name in front of parent chain.

  3. Example O C-C-O-C-C-C Parent: ethane ethanoate  Branch: propyl Final name: propylethanoate

  4. Example O C-C-C-C-O-C-C- Parent: butane butanoate  Branch: ethyl Final name: ethyl butanoate

  5. Draw: pentylhexanoate O C-C-C-C-C-C-O-C-C-C-C-C

  6. Name: O C-O-C-C-C Parent: propane propanoate  Branch: methyl Final name: methyl propanoate

  7. Amines (p. 51) • Organic compounds that are derivatives of ammonia (NH3 ). R-N-R” R’ • Naming: • Name the branches (R, R’, R”) in alphabetical order; they can also be halogens. • Add the word amine at the end.

  8. Primary amine • (1 hydrogen is replaced by an alkyl group) C-N-H H • methyl amine

  9. Secondary amine • (2 hydrogens are replaced by alkyl groups) C-N-C-C H • ethyl methyl amine

  10. Tertiary amine • (3 hydrogens are replaced by alkyl groups) C-N-C-C C-C-C • ethyl methyl propyl amine

  11. Draw: pentylpropyl amine C-C-C-C-C-N-C-C-C H
