Read: pg 409-431 AND 436-439 (up to F.3)

HW:

Extra credit (5 pts): Read pg. 194-196, hand-in example 8.3 and Practice Exercise)

Objectives:

  1. Recognize the structure of acetic anhydride and phosphorous containing anhydrides.
  2. Be able to draw structures and give examples of carboxylic acids.
  3. Know common nomenclature for carboxylic acids (-ic acid and a ,b ,g ,d positions).
  4. Know IUPAC names for carboxylic acids methanoic acid to decanoic acid (drop the e in methane and add oic acid).
  5. Know why a water insoluble acid will dissolve if you add some base to the water.
  6. Know that the salt formed by the addition of base ends in -ate and begins with an inorganic metal (e.g. sodium)
