Fischer esterification is an example of nucleophilic acyl substitution based on the electrophilicity of the carbonyl carbon and the nucleophilicity of an alcohol. However, carboxylic acids tend to be less reactive than esters as electrophiles. Additionally, in dilute neutral solutions they tend to be deprotonated anions (and thus unreactive as electrophiles). Though kinetically very slow without any cat… WebFischer Esterification Conclusion Report And Discussion Example (300 Words) - PHDessay.com. CyberLeninka.
