![Esterification is the reaction of a carboxylic acid (RCOOH) with an alcohol (ROH) to form an ester (RCOOR) with loss of water. Equation [1] is an example of an intermolecular esterification reaction. Equation [2] is an example of an intramolecular esterification reaction, that is, the carboxylic acid and alcohol are contained in the same starting material, forming a cyclic ester as product. The equilibrium constants for both reactions are given. Explain why K is different for these two apparently similar reactions eq ethyl acetate H2O Keq-1000 OH](http://img.homeworklib.com/questions/64e86c30-fb1f-11eb-b5ba-5db502c79178.png?x-oss-process=image/resize,w_560)

A Fischer Esterification reaction forms an ester from a carboxylic acid and an alcohol. This reaction is catalyzed with sulfuric acid (H2SO4). Which of the following statements below correctly describe an acid catalyzed reaction. Mark all the statements that are correct. Once the acid is consumed the reaction will stop until additional acid is added. An excess of acid is needed to get this reaction to run to completion. Acid is regenerated during the reaction. Only a small amount of...

This is a Fischer Esterification using the alcohol, methanol,
and the carboxylic acid, butyric acid, to create the ester, methyl
butanoate (smells like apple). After refluxing methanol, butyric
acid, and concentrated sulfuric acid, a separatory flask was used
and the ester was extracted using ice water, then diethyl ether,
then 2 portions of sodium carbonate, and a saturated sodium
chloride brine solution. Anyhydrous sodium sulfate was used after
separation to dry the ester. Please help!!

We made esters from carboxylic acids and alcohol. (for one of them, acetic acid + isopentyl alcohol + couple drops of sulfuric acid). Could someone please explain those. Thank you 1. Consider if we had prepared high molecular weight esters, what problems would this pose regarding our method of analysis 2. We used sulfuric acid as a catalyst, but carboxylic acids are a reagent in this reaction. Would simply using excess carboxylic acid work as efficiently as sulfuric acid to...

Why is so much NaOH used in the extraction? Recall that only four drops (small amount) of sulfuric acid were used as a catalyst. Esters are an important class of organic molecules, which are formally derived from alcohols and carboxylic acids. Esters occur widely in nature and are often an important...
