In esterification the reactivity of alcohols is :

In the esterification reaction of alcohols

In esterification reaction of ethyl alcohol with acetic acid in presence of dry HCl gas

The reactivity of ethyl chloride is :

R-OH + HX to R -X + H_(2)O In the above reaction the reactivity of different alcohols is

R-OH + HX to R -X + H_(2)O In the above reaction the reactivity of different alcohols is

A : In esterification reaction alcohol act as nucleophile . R : In this reaction O - H bond of alcohol is broken .

Statement -1 Phenols cannot be converted into esters by direct reaction with carboxylic acids whereas alcohols can be Statement -2 This is due to the fact that the esterification reaction is exothermic for alcohols but slightly endothermic for phenols.

Alcohols undergo acid catalysed elimination reactions to produce alkenes. Because water is lost in the elimination , this reaction is called dehydration reaction. Secondary and tertiary alcohols always give E1 reaction in dehydration. Primary alcohols whose beta -carbon is branched also give E1 reaction. The reactivity of alcohol for elimination reaction is tertiary alcohol > secondary alcohol > Primary alcohol. Which of the following dehydration product (major ) is incorrect ?

What is the correct order of reactivity of alcohols in the following reaction ? R-OH+HCl overset(ZnCl_(2))to R-Cl+H_(2)O
