Vedclass · Answer

(A) The nucleophilic aromatic substitution reaction of chlorobenzene derivatives with aqueous $NaOH$ proceeds via the formation of a Meisenheimer complex,which is stabilized by electron-withdrawing groups (EWGs) at the ortho and para positions. $1$. The rate of nucleophilic aromatic substitution increases with the number of electron-withdrawing groups (like $-NO_2$) present at the ortho and para positions relative to the chlorine atom. $2$. $1$-chloro-$2,4,6$-trinitrobenzene has three strong electron-withdrawing $-NO_2$ groups (two at ortho,one at para positions),which significantly stabilize the negative charge in the intermediate transition state,making it the most reactive towards nucleophilic substitution. $3$. $1$-chloro-$4$-nitrobenzene has only one $-NO_2$ group at the para position,making it less reactive than the trinitro derivative. $4$. Chlorobenzene and $1$-chloro-$4$-(dimethylamino)benzene (where $-N(CH_3)_2$ is an electron-donating group) are much less reactive. Therefore,$1$-chloro-$2,4,6$-trinitrobenzene undergoes hydrolysis most readily.

Which chloroderivative of benzene among the following would undergo hydrolysis most readily with aqueous $NaOH$ to furnish the corresponding hydroxy derivative?
