Answer 1

Answer:

Explanation:

The task in this question is to match the right procedure to its purpose. It explains the procedure for the preparation of Fischer Esterification. Fischer Esterification Mechanism should incorporate the ceaseless expulsion of water from the framework or the use of a huge amount of excess alcohol since the general reaction is reversible. Fischer Esterification act as an organic reaction that is utilized to change over carboxylic acids within the sight of excess alcohol and a solid corrosive catalyst (acid) to give an ester as the eventual outcome.
