Which of the following catalysts is used in the below reaction?
Correct answer: A. Conc. H2SO4
- A. Conc. H2SO4
- B. Purnice stone
- C. Pt
- D. Ni
Explanation
Esterification process is a slow process when it is performed at room temperature also the process does not complete at all in the room temperature. So to complete the process of esterification there should be something to complete the process as well as to speed up the process. Thus concentrated sulphuric acid is added. It is a catalyst which will speed up the process and esterification will proceed speedily and complete on time. Also concentrated sulphuric acid has a property to remove water. Therefore it also acts as a dehydrating agent. After adding this will take reaction in the equilibrium position and will be able to give a greater yield of ester as result.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
