Which is most reactive of the following ?

Options

A. Ethyl acetate
B. Acetic anhydride
C. Acetamide
D. Acetyl chloride

Answer

D

Explanation

The order of reactivity of acid derivatives towards different reactions decreases in the order,
`RCOCl gt (RCO)_(2)O gt RCOOR. gt RCONH_(2)` In other words, the reactivity decreases as the basicity of the leaving group increases i.e.,
`Cl^(-) lt RCOO^(-) lt RO^(-) lt NH_(2)^(-)`
