sir from the carbanion, write the resonance structure for the enolate ion...... systematicity of writing the mechanism is lost sir...Also mechanism wont stop to the beta keto ester in the step 2 (yield is very less in this step).. In step 3..there will be an acid base reaction between beta keto ester and ethoxide ion to give a resonance stabilised carbanion.....and then in the step 4, hydrolysis of the carbanion gives beta keto ester in good yield. mechanisms have to be written with lone pair of electrons in all the steps wherever it is necessary... Please follow Organic Chemistry By Graham Solomons ,Organic Chemistry by Fransis A carey.....Organic Chemistry by wade Junior, Organic Chemistry by Jenice Smith , Organic Chemistry by Mark .G.Loudon......These books will be very helpful to write the mechanisms systematically with lone pair of electrons.
Sir....always write lone pair of electrons on the carbanion and then negative charge and similarly on the anion of oxygen ( you have to write three lone pair on anion of oxygen and negative charge and one lone pair on carbon and negative charge)and write the curly arrow from oxide ion to the electron deficient carbon when ethoxide ion is lost. Systematic way of writing the mechanism is lost. The step 2 is a nucleophilic addition followed by elimination which is nothing but the nucleophilic substitution at the sp2 carbon of ester.
Awesome sir... Don't and all give up your work.. ✨✨✨We have been so beneficial using this...Thanks a lot Sir 😌😌🌟
Thank you so much ....
Chala chala baga explain chesaru chusi subscribe chesukunnanu sir
Good
Sir can you uplode mixed claisen condensation video please
Nice explanation sir
Thank you sir good explanation sir
Well explained.. Thankyou Sir
You are most welcome
Thank you so much Sir
Xlent sir.. tqq sirr
Sir I will request to you explain melonic ester sir please
Why the nature of alpha hydrogen in ketones mentioned in this video is more acidic than beta hydrogen?
Due to the electronegativity of oxygen atom which is nearer to alpha hydrogen. So always more acidic than beta.

Also write the IUPAC name of the ethyl aceto acetate...i.e., ETHYL - 3 - OXOBUTANOATE.
