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.

Show how to synthesize carboxylic acids from oxidation of alcohols and aldehydes,carboxylation of Grignard reagents, oxidative cleavage of alkenes and alkynes,hydrolysis of nitriles, and oxidation of alkylbenzenes
How many esters can be formed by ethylene glycol with formic and acetic acids? (One or both of the –OH groups of ethylene glycol can react.)
Modified true or false. If statement is true, write TRUE, otherwise change the italicized words/phrases in the statement. Cations in hard water like Ca2+ and Mg2+ can form precipitates with carboxylates in soaps, reducing their efficiency as cleansing agents. If an ester is to be prepared with ethanol, using at least 70% ethanol could maximize the yield.
Indicate the CORRECT alternative: a) Acid halides react only in the presence of a catalyst. b) The reaction of an acid chloride with an alcohol produces less of an ester than using the Fischer reaction. c) The nucleophilic substitution reaction in acid derivatives occurs through an SN1 mechanism. d) Reduction of an ester with LiAlH4 yields only secondary alcohols. e) Hydrolysis of an amide in an acid medium produces a carboxylic acid and a protonated amine.
