Terephthalic acid is an important chemical used in the manufacture of polyesters and plasticizers. It contains only C, H, and O. Combustion of 19.81 mg terephthalic acid produces 41.98 mg CO2 and 6.45 mg H2O. If 0.250 mol of terephthalic acid has a mass of 41.5 g, determine the molecular formula for terephthalic acid.
Tuesday, February 7, 2017 Organic Chemistry II Week 2 Notes - Converting a carbonyl group to an enol- this can be done in acidic and basic conditions • Basic Conditions - 1. A base deprotonates a hydrogen on an alpha carbon (carbon adjacent to the carbonyl group) - 2. The negatively charged carbon than forms a pi bond with the carbonyl carbon - 3. Simultaneously, the pi bond on the carbonyl group breaks and the electrons move to the oxygen - 4. The negatively charged oxygen is protonated to form an enol • Acidic Conditions - 1. The oxygen apart of the carbonyl group is protonated by an acid - 2. The deprotonated acid removes a proton from a carbon next to the carbonyl group - 3. This causes the
