What Is The Difference Between Neutralization Reaction And Esterification

Is esterification reaction a neutralisation reaction?

According to me , its not !Beacuse neutralisation reaction requires and acid and a base while in esterification the reaction takes place between n carboxylic acid and an alcohol (not a base)Second thing , neutralisation gives away salt and water as product ,not esters.And the last , esterification can be reversed practically unlike neutralistion that says if we react salt and water we should get acid and a base (which never happens as it is a irreversible reaction)Thats all that I know.I hope this helps !Thanks For A2A !

Difference between precipation and neutralisation reaction?

Guys anyone please give full detail upon this...I have my exams after 4 days and confused between these....I would really appreciate and thankfull to anyone who answered this.

Are all neutralization reactions non-redox reactions?

Yes. How am I so sure and certain? For each acid base reaction's chemical equation that eventually forms a salt and water, check if there's any change in oxidation state. There won't be and hence it's a non redox reaction.

What is the difference between dehydration reactions and neutralisation reactions (between an acid and a base)?

Any reaction in which water is removed is technically a dehydration reaction.But when an inorganic acid reacts with an inorganic base (usually in aqueous solutions), the reaction is known as “neutralization” even though one of the products is water. This is because the acidic nature of the acid and the basic nature of the base disappear (“become neutralized”) since the products are salt (which is neutral) and water (which is neutral). Please note that in these reactions, whatever acid or base is used, the water is always formed by the combination of H+ ions and OH- ions (the charges are neutralized). No catalysts or special reagents to remove the water (dehydrating agents) are required in such reactions. These are not considered as dehydration reactions. Examples:Formation of ester by the reaction between organic acid and alcohol is technically a dehydration reaction, but it is more commonly called “esterification” reaction (only because the emphasis is on the formation of esters when the reaction is discussed in chemistry classes). A dehydrating agent like concentrated sulfuric acid has to be used in such reactions. The H atom from one molecule and the OH group from another molecule are “stripped off” by the dehydrating agent to make water (This statement may not be correct from the mechanistic point of view, but that is not relevant to this discussion). Example:Some other examples of dehydration reactions are:Formation of ether from two alcohol moleculesFormation of alkene by dehydration of alcoholRemoval of water of crystallization from hydrated salts by heating to get anhydrous salt may also be considered as dehydration. No dehydrating agents are used in this case.So, to conclude, we may consider organic reactions in which water is removed with the help of dehydrating agents like anhydrous alumina, concentrated sulfuric acid etc. as “proper” dehydration reactions.

What is an esterification reaction? What are it’s uses?

An esterification reaction is a type of condensation reaction (removal of water). For an acid catalysed esterification, a carboxylic acid is heated with alcohol in the presence of an acid to form an ester. Since this reaction is reversible, water must be continuously removed from the process so that the ester bond is not hydrolysed (broken down by water) to reform the original reactants.As you can see, an OH is removed from the carboxylic acid and an H from the alcohol to form H2O - water.Esters have the functional group -COO-, with one oxygen double bonded to the carbon and the other single bonded to the carbon.Esters have some really fantastic smells which imitate that of fruits and flowers. They are often used as artificial flavourings or scents in food and perfumes. Esterification is useful because it produces esters using simple laboratory equipment and non-toxic reagents.

What is a neutralisation reaction?

A neutralization reaction is one in which an acid and a base generally react to form the respective salt, and water, only. Eg:NaCl + H2SO4 = Na2SO4 + H2O.The acid and base neutralize the acidity and basicity of each other and therefore it is termed as neutralization.

8. Name the ester produced from an esterification reaction between butanoic acid and ethanol.?

Esterification
Syllabus reference (October 2002 version)
5. Esterification is a naturally occurring process which can be performed in the laboratory
Students learn to:

* describe the differences between the alkanol and alkanoic acid functional groups in carbon compounds

* identify the IUPAC nomenclature for describing the esters produced by reactions of straight-chained alkanoic acids from C1 to C8 and straight-chained primary alkanols from C1 to C8

* explain the difference in melting point and boiling point caused by straight-chained alkanoic acid and straight-chained primary alkanol structures

* identify esterification as the reaction between an acid and an alkanol and describe, using equations, examples of esterification

* describe the purpose of using acid in esterification for catalysis

* explain the need for refluxing during esterification

* outline some examples of the occurrence, production and uses of esters

Students:

* identify data, plan select equipment and perform a first-hand investigation to prepare an ester using reflux

* process information from secondary sources to identify and describe the uses of esters as flavours and perfumes in processed foods and cosmetics

Abstract

A new, large-scale process was developed for the enzymatic production of low molecular weight flavour esters in organic solvent. Solutions for the elimination of substrate and product inhibitions are presented. The excess water produced during the process was continuously removed by hetero-azeotropic distillation and esters were produced at yields of over 90%.

Why is sodium bicarbonate used in a Fischer Esterification reaction?

Precisely. The Fischer esterification is done typically with an acid catalyst. You can add some drops of sulfuric acid, or saturate the solution with HCl gas.

When you work it up, a wash with a bicarbonate solution will neutralize any mineral acids you may have added in the reaction, and also remove any unreacted acid as its sodium salt.

Your ester is extracted into the organic phase. Everything else is left behind in the aqueous phase.
