Arrange the following compounds in order of their decreasing reactivity with an electrophile, `E^+` (A)chlorobenzene , (B)2,4-dinitrochlorobenzene , (C )p-nitrochlorobenzeneA. C gt B gt AB. B gt C gt AC. A gt C gt BD. A gt B gt C |

Answer» Correct Answer - C Electron-withdrawing groups in the benzene ring decrease the reactivity towards electrophilic substitution. Since Cl is a weaker electron-withdrawing group that `NO_2`, therefore , chlorobenzene (A) is more reactive than p-nitrochlorobenzene (C ) which , in turn, is more reactive than 2,4-dinitrochlorobenzene (B), i.e., option (c) is correct. |
