  1. Esters (p. 49) • Organic compounds that began as acids and were reacted to become esters. • General form: O O R-C-OH R- C-O-R

  2. Naming: • Parent Chain • The part connected to the double bonded oxygen (that is carbon #1) • It is named last • Name as an alkane (remove the “e”) • Ends in –oate (pronouced “o” ate)

  3. Naming: • Branches • Named first • Part connected to the single bonded oxygen • End in –yl • Example: Propylethanoate • O C-C-O-C-C-C 2 1 1 2 3 (parent) (alkyl branch)

  4. Example • O C-C-O-C-C-C-C 2 1 1 2 3 4 Ethyl Butanoate

  5. Draw: PentylHexanoate O C-C-C-C-C-O-C-C-C-C-C-C 5 4 3 2 1 1 2 3 4 5 6

  6. Example: • OR O C-C-C-C-C-C-O-C-C-C-C-C 6 5 4 3 2 1 1 2 3 4 5

  7. Amines (p. 51) • Organic compounds based on NH3 • General form: R” R- N -R’ • Naming: • Carbon branches ( -yl) replace hydrogens • Put in alphabetical order • Add amine at the end

  8. Example: Name C – C – C – C – C – C – C – C – C C - C - C – C – N - C – C – C – C –C Butyl nonylpentyl amine

  9. Example: C – C – N - C - C Cyclobutyl diethyl amine

  10. Name: C – C - C C - C - C -C – C – N - H pentylpropyl amine

  11. H C - C - C - C -C - C- N -H hexylamine
