Provide a mechanism (using curly arrows) for the Fischer esterification of p-bromobenzoic acid with sulphuric acid and methanol

In biochemical reactions, decarboxylation of carboxylic acids typically takes place for-keto carboxylic acids. Justify a rational why nature opted for-keto carboxylic acid decarboxylation. Among the following types of biochemical reactions, ester hydrolysis, rearrangement reactions, water elimination reactions, and anhydride hydrolyses, which one is the most favorable one. Rank the above reactions types in the order of being the most to least favorable reaction

Two reactions occur when sodium hydroxide is added to methyl salicylate. One is immediate and one only occurs with reflux over time. What type of reaction occurs immediately and with which functional group on methyl salicylate does it react? What type of reaction occurs with reflux over time and with which functional group on methyl salicylate does it react?

Chemistry Show how to prepare N-ethylpropanamide from propanoic acid at or below room temperature .       Use standard conventions to write a mechanism for the intramolecular Fischer esterification of 5-hydroxyhexanoic acid in the presence of an acid catalyst, H-A.

What is the structure of the compound formed when 5-nitro-2-furaldehyde reacts with 4-cyanophenyl hydrazine hydrochloride?

In detail, explain how to separate a mixture of naphthalene, byphenyl-4-carboxylic acid, and 4-chloroaniline.

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.
