acid hydrolysis of ester is which order reaction
What happens when esters are hydrolysed by water?
That is exactly what happens when esters are hydrolysed by water or by dilute acids such as dilute hydrochloric acid. The alkaline hydrolysis of esters actually involves reaction with hydroxide ions, but the overall result is so similar that it is lumped together with the other two. The reaction with pure water is so slow that it is never used.
What is the difference between acidic hydrolysis and esterification?
The hydrolysis of esters can be catalyzed by either an acid or a base, with somewhat different results. Acidic hydrolysis is simply the reverse of esterification. The ester is heated with a large excess of water containing an acid catalyst. Like esterification, the reaction is reversible and does not go to completion.
