Could you please write this reaction in reverse with all the intermediate steps? Thank you
Homework Answers
It is acidic hydrohysis of ester.
* Acid provides H+ which works as neucleophile and oxygen attacks on it.
Than H2O attacks as neucleophile on carbonyl carbon which bears partially positive charg
* Carboxylic acid & alcohol formed as product.
