Explanation / Answer

most reactive: butanoyl chloride

acetic propionic anhydride

butyl acetate

least reactive: N,N-diphenylethanamide

Explanation: Acid chlorides are most reactive in nucleophilic acyl substitution reaction due to electron withdrawing nature of chloride ion. Amides are least reactive due to more electronegative nature of nitrogen atom.
