Which of the following orders regarding the base strength of a leaving group in a reaction of an acid derivative with a nucleophile is correct :

Which of the following orders regarding the base strength of a leaving group in a reaction of an acid derivative with a nucleophile is correct :

Give the order of reactivity of various acid derivatives towards nucleophilic substitution. Solution

Give the order of reactivity of various acid derivatives towards nucleophilic substitution. Solution

Correct order of reactivity of following acid derivatives is : MeCOCI MeCON_(3) MeCOOCOMe MECOOMe

The correct reactivity order with the nucleophile is :

The reactivity of acid derivatives in general follows the order : The above order of reactivity can be explained in terms of the : (i) Basicity of leaving group (ii) Resonance effect (iii) Inductive effect Weaker is the basic character of leaving group, more is the reactivity of acid derivative. In general, all the acid derivatives show resonance as follows: More is the stablization, lesser is the reactivity and vice-versa. Which among the following ester is most reactive towards nucleophilic attack ?
