Question

Which of the following sequences represents the correct decreasing order of reactivity of carboxylic acid derivatives towards nucleophilic acyl substitution?

Answer: A

💡 Solution & Explanation

Reactivity correlates with leaving group ability, which is inversely proportional to basicity. The chloride ion is the weakest base (best leaving group), making acyl halides most reactive. Amides are the least reactive.
