Write the mechanism for the reaction of the esterification of salicylic acid to methyl salicylate?

It's going to be hard to show a mechanism using this website, so I suggest you look up "esterification" and learn the mechanism.

An example of a compound form when carboxylic acid and alcohol react.\n\nAn equation for such a reacton is\n\n R-COOH + R'-OH = R-COO-R' + H2O \n\nthe -COOH group and the -OH group lose a water and become a -COO- linkage: \n\n\nwhere R and R' represent organic groups.

Presuming that bromine is getting reduced to Br(-) and bisulfite is getting oxidized to sulfate (not including the spectator sodium ion):\n\nReduction half-reaction\nBr2 + 2e ---->  2Br(-)\n\nOxidation half reaction\nHSO3(-) + H2O ----->  SO4(2-) + 2e + 3H(+)\n\nOverall Reaction:\nBr2 + HSO3(-) + H2O ---->  SO4(2-) + 2Br(-) + 3H(+)

* The process begins with the oxidation of pyruvate, producing one CO2, and one acetyl-CoA.\n    * Acetyl-CoA reacts with the four carbon carboxylic acid, oxaloacetate--to form the six carbon carboxylic acid, citrate.\n    * Through a series of reactions citrate is converted back to oxaloacetate. This cycle produces 2 CO2 and consumes 3 NAD+, producing 3NADH and 3H+.\n    * It consumes 3 H2O and consumes one FAD, producing one FADH+.\n    * 1st turn end= 1 ATP, 3 NADH, 1 FADH2\n    * Since there are two molecules of Pyruvic acid to deal with, the cycle turns once more.\n    * The complete end result= 2 ATP, 6 NADH, 2 FADH2

As I recall, you react the hydroxy group on the benzene ring with acetyl annhydride and it makes the hydroxy group into an ester.

This is a addition-elimination reaction (http://www.chem.ucalgary.ca/courses/351/Carey/Ch23/ch23-3-3.html). can be accelerated by lewis acids.

It is a nucleophilic substitution reaction, where the nucleophile -OH from KOH replaces -Cl from 1-chlorobutane; this forms KCl and 1-butanol as products.\n\nKOH + CH3-CH2-CH2-CH2Cl ---> KCl + CH3-CH2-CH2-CH2OH

CH3CONH2 + Na+-OH ---->  CH3COO -Na+ +  :NH3\n\nThis is a amide hydrolysis reaction, similar to the hydrolysis of an ester. Hydroxide attacks carbonyl to give tetrahedral intermediate. Explulsion of an amide ion gives a carboxylic acid, which is deprotonated quickly to give the carboxylate ion and ammonia.

The second one:\nAF + H --> AFM + TM\n\nActivation E: +10KJ/mol is moderate\nHeat of Rx= +5.2 KJ/mol is positive, making this an endothermic reaction (requires the input of heat or energy to accomplish).\n\nSee the site below:

This is an esterification, \nButanoic Acid (CH3CH2CH2CO2H)+ ethanol (HO-CH2CH3), in basic media, yields ethyl butyrate. \n\nCH3CH2CH2CO2H + HO-CH2CH3 --> CH3CH2CH2COO-CH2CH3

It is used as a rubefacient in deep heating liniments, and in small amounts as a flavouring agent. It is also used to provide fragrance to various products.\n\nIt also has the property of fluorescence, converting ultraviolet light into visible blue light.\n\nMethyl salicylate's odor is nearly indistinguishable from "sour-apple".\n\nMethyl salicylate produces the familiar odor and flavor of oil of wintergreen. This chemical relative of aspirin also relieves the inflammation that causes headaches and muscle pain. Concentrated methyl salicylate is toxic, especially to children, but small amounts may be used as flavorings and in topical creams.

The answer is B, butyric acid, or the ester of it.

The acetyl salicylic acid undergoes ester hydrolysis on long term standing to produce acetic acid (vinegar) and salicylic acid.  The problem was that salicylic acid was tough on stomachs and a means of 'buffering' the compound was searched for. The first person to do so was a French chemist named Charles Frederic Gerhardt. In 1853, Gerhardt neutralized salicylic acid by buffering it with sodium (sodium salicylate) and acetyl chloride, creating acetylsalicylic acid. Gerhardt's product worked but he had no desire to market it and abandoned his discovery. \n\nIn 1899, a German chemist named Felix Hoffmann, who worked for a German company called Bayer, rediscovered Gerhardt's formula. Felix Hoffmann made some of the formula and gave it to his father who was suffering from the pain of arthritis. With good results, Felix Hoffmann then convinced Bayer to market the new wonder drug. Aspirin was patented on March 6, 1889. \n\nThe folks at Bayer came up with the name Aspirin, it comes from the 'A" in acetyl chloride, the "spir" in spiraea ulmaria (the plant they derived the salicylic acid from) and the 'in' was a then familiar name ending for medicines. \n\nAspirin was first sold as a powder. In 1915, the first Aspirin tablets were made. Interestingly, Aspirin ® and Heroin ® were once trademarks belonging to Bayer. After Germany lost World War I, Bayer was forced to give up both trademarks as part of the Treaty of Versailles in 1919.
