Correct Answer: A
Solution:
Amongst aldehyde & the acid derivatives, acid chloride are the most susceptible to nucleophilic attack due to strong -I effect & weak +R effect of the Cl-atom as a result of which carbonyl carbon has the highest electron deficiency. The actual order is MeCOCl >MeCOOCOMe >MeCOOMe >MeCHO.
