group present at para
position shows both -M and -I effects facilitates the reaction towards 
. Here, the halogen group show the reaction rate in the following manner- 
.
This can be understood by the following mechanism.
To create a nucleophilic center at the benzene ring, 
must be more electronegative. Therefore halogen will follow the following order, 
Here rate of 
reaction
F Cl Br I
