WebFischer Esterification is an organic reaction which is employed to convert carboxylic acids in the presence of excess alcohol and a strong acid catalyst to give an ester as the final product. This ester is formed along with … WebExamination of the Fischer esterification mechanism continues. Recall the overall reaction: LH + CH3OH + H-CH: CH3 H-CI: Part 1 of the Fischer esterification involves CH OH addition to form the tetrahedral intermediate. Part 2 involves loss of H0 from the tetrahedral intermediate to form ester.
