Explain the reactivity of acyl compounds in the order:

Aryl halides are extermely less reactive towards nucleophilic substitution. Predictand explain the order of reactivity of the compounds towards nucleophilic substitution.

The relative reactivities of acyl compounds towards nucleophilic substitution are in the order of :

The relative reactivities of acyl compound towards nucleophilic substitution are in the order of

The relative reactivities of acyl compound towards nucleophilic substitution are in the order of

Relative reactivity of carbonyl compounds towards nucleophile? 1) Acyl halide > Acid anhydride > Aldehyde > Carboxylic acid. 2) Carboxylic acid > Aldehyde > Acid anhydride > Acyl halide. 3) Acyl halide > Aldehyde > Acid anhydride > Carboxylic acid. 4) Acid anhydride > Acyl halide > Carboxylic acid > Aldehyde.
