Vedclass · Answer

(C) The reactivity of acid chlorides towards hydrolysis depends on the magnitude of the positive charge on the carbonyl carbon atom.Electron-withdrawing groups $(EWG)$ increase the positive charge on the carbonyl carbon,thereby increasing reactivity.Electron-donating groups $(EDG)$ decrease the positive charge on the carbonyl carbon,thereby decreasing reactivity.The substituents at the para-position are:$(i)$ $-H$ (no effect)$(ii)$ $-NO_2$ (strong $EWG$)$(iii)$ $-CH_3$ ($EDG$ via hyperconjugation)$(iv)$ $-CHO$ $(EWG)$Comparing the strength of $EWG$,$-NO_2$ is a stronger electron-withdrawing group than $-CHO$.Thus,the order of reactivity is: $(ii) > (iv) > (i) > (iii)$.

Consider the following compounds:
$(i) \, C_6H_5COCl$
$(ii) \, p-NO_2-C_6H_4-COCl$
$(iii) \, p-CH_3-C_6H_4-COCl$
$(iv) \, p-CHO-C_6H_4-COCl$
The correct decreasing order of their reactivity towards hydrolysis is:
