Vedclass · Answer

(C) The rate of hydrolysis of acid chlorides $(RCOCl)$ depends on the electrophilicity of the carbonyl carbon. Electron-withdrawing groups $(EWG)$ increase the positive charge on the carbonyl carbon,making it more susceptible to nucleophilic attack,thus increasing the rate of hydrolysis. Electron-donating groups $(EDG)$ decrease the positive charge on the carbonyl carbon,making it less susceptible to nucleophilic attack,thus decreasing the rate of hydrolysis. Comparing the substituents: $1$. $-NO_2$ is a strong $EWG$ ($-I$ and $-M$ effect). $2$. $-H$ (no substituent). $3$. $-CH_3$ is an $EDG$ ($+I$ and hyperconjugation). $4$. $-OCH_3$ is a strong $EDG$ ($+M$ effect). Therefore,the correct order of reactivity is: $p-NO_2-C_6H_4COCl > C_6H_5COCl > p-CH_3-C_6H_4COCl > p-OCH_3-C_6H_4COCl$.

List-$I$ (Chemical Reaction)	List-$II$ (Reagent used)
$(a)$ $CH_{3}COOCH_{2}CH_{3} \rightarrow CH_{3}CH_{2}OH$	$(i)$ $CH_{3}MgBr / H_{3}O^{+}$ ($1$ equivalent)
$(b)$ $CH_{3}COOCH_{3} \rightarrow CH_{3}CHO$	$(ii)$ $H_{2}SO_{4} / H_{2}O$
$(c)$ $CH_{3}C \equiv N \rightarrow CH_{3}CHO$	$(iii)$ $DIBAL-H / H_{2}O$
$(d)$ $CH_{3}C \equiv N \rightarrow CH_{3}COCH_{3}$	$(iv)$ $SnCl_{2}, HCl / H_{2}O$
