Arrange the following set of compounds in order of their decreasing relative reactivity with an electrophile, E+ (a) Chlorobenzene, 2,4-dinitrochlorobenzene, p-nitrochlorobenzene (b) Toluene, `p-H_3C–C_6H_4–NO_(2), p-O_2N–C_6H_4–NO_2`.A. `(iii) gt (ii) gt (i)`B. `(ii) gt (iii) gt (i)`C. `(i) gt (iii) gt (ii)`D. `(i) gt (ii) gt (iii)` |
|
Answer» Correct Answer - C In (i), one deactivating group (-Cl) is present. In (ii), 3 deactivating groups (`2-NO_(2)` and 1-Cl) are present, and in (iii), 2 deactivating groups (`-NO_(2)` and -Cl) are present. So order is `(i) gt (iii) gt (ii)`. |
