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 stabilization, lesser is the reactivity and vice -versa.
Which among the following acid halides is the most reactive?
A. `CH_(3)COBr`
B. `CH_(3)COCl`
C. `CH_(3)COI`
D. All are equally reactive
