reactivity of carboxylic acid derivatives in order
Which of the following is the correct order for the reactivity of carboxylic acid derivatives from least reactive to most?
The order of reactivity of carboxylic acid derivatives is Acid Chloride > Acid Anhydride > Ester > Amide.
Hence correct option.Which derivative of carboxylic acid is most reactive?
Inductive electron withdrawal by Y increases the electrophilic character of the carbonyl carbon, and increases its reactivity toward nucleophiles.
Thus, acyl chlorides (Y = Cl) are the most reactive of the derivatives.What is the reactivity order of acyl derivatives of carboxylic acid towards nucleophiles?
The relative reactivity of carboxylic acid derivatives toward nucleophile substitutions is related to the electronegative leaving group's ability to activate the carbonyl.
The more electronegative leaving groups withdrawn electron density from the carbonyl, thereby, increasing its electrophilicity.
