    What type of groups produce + l-effect ?

    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. Acid derivatives although contain -overset(O)overset(||)C- group, yet do not undergo the usual properties of carbonyl group. It is due to
