Question

We have studied Fischer esterification, in which a carboxylic acid is reacted with an alcohol in the presence of an acid catalyst to form an ester. Suppose that you start instead with a dicarboxylic acid such as terephthalic acid and a diol such as ethylene glycol. Show how Fischer esterification in this case can lead to a macromolecule with a molecular weight several thousand times that of the starting materials. HO, OH poly(ethylene terephthalate) (РET) НО HO, 1,4-Benzenedicarboxylic acid (Terephthalic acid) 1,2-Ethanediol (Ethylene glycol) the material produced in this reaction is a high- molecular-weight polymer, which can be fabricated into Mylar films and into the textile fiber known as Dacron polyester.

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

Esterication is the reaction of a carboxylic acid (RCOOH) with an alcohol (R'OH) to form an ester (RCOOR') with loss of water. Equation [1] is an example of an intermolecular esterication reaction. Equation [2] is an example of an intramolecular esterication reaction; that is, the carboxylic acid and alcohol are contained in the same starting material, forming a cyclic ester as product. The equilibrium constants for both reactions are given. Explain why Keq is different for these two apparently similar reactions.

In an esterification reaction, a carboxylic acid reacts with an excess of alcohol in acidic conditions to form an ester. Draw the structure of the ester product in the reaction between pentanoic acid and 1‑propanol. pentanoic acid+ 1-propanol= ester+ H20 structure of ester product needed
