In a compound electrophilic substitution has occurred the substituents E are methyl `-CH_(3)Cl-CCl_(3)` and `-CHCl_(2)` the correct increasing order towards electrophilic substitution is

Options

A. `-CH_(3) lt CH_(3)Cl lt -CHCl_(2) lt -CCl_(3)`
B. `-CH_(3) lt -CHCl_(2) lt -CH_(2)Cl lt-C Cl_(3)`
C. `-C Cl_(3)lt-CH_(2)Cl lt -CHCl_(2) lt -CH_(3)`
D. `-C Cl_(3) lt -CHCl_(2) lt -CH_(2)Cl lt -CH_(3)`

Answer

D

Explanation

Since halogen atom (X) has negative inductive effect the replacement of H in `-CH_(3)` by halogen decreases the electron-releasing tendency of the group and, finally, converts it into an electron-withdrawing group:
