Lab: Preparation of Esters Essay - 739 Words.

Esters are derived from carboxylic acids and alcohols with the presence of a catalyst. A carboxylic acid contains the -COOH group, and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. Sulfuric acid (H2SO4)is used as a catalyst for this reaction in order to accelerate the rate at which the product is formed.

Esters are known for their pleasant smells such as perfumes and artificial flavorings in contained labs. They are formed when a carboxylic acid reacts with alcohol and a strong acid such as a catalyst called sulfuric acid (H2SO4) for this lab. The structural formula for esters can be represented as R-COO-R’.Conclusion: The purpose of this lab was to produce esters from the acid catalyzed reaction between an alcohol and a carboxylic acid. We were successful in achieving this goal, as the product has the distinct “banana” smell- which indicates the presence of esters. Overall this lab was successful.Conclusion Conclusion paragraph This includes a summary of the introduction and the three main parts of the essay — the body, and a final statement which gives the reader the idea that the essay subject matter has come to an end.
