Which of the following is most reactive towards nucleophilic substitution reaction?
Options
- AEthyl acetate
- BAcetic anhydride
- CAcetamide
- DAcetyl chloride
Correct answer
D. Acetyl chloride
Step-by-step solution
The order of reactivity of acid derivatives towards different reactions decreases in the order,
RCOCl > ( RCO{)}_{2}O > RCOOR^{′} > RCON{H}_{2}
In other words, the reactivity decreases as the basicity of the leaving group increases i.e.,
RCOCl > ( RCO{)}_{2}O > RCOOR^{′} > RCON{H}_{2}
In other words, the reactivity decreases as the basicity of the leaving group increases i.e.,
