The halide which will not react with benzene in presence of anhydrous $AlC{l}_3$ is

Given data : It is given to identify the halide which will not react with benzene in presence of anhydrous $AlC{l}_3$ is

Explanation

Among the given options $C_6{H}_{5}Cl$ is an Aryl halide and it is less reactive so it does not undergo a reaction with benzene in the presence of $AlC{l}_3$.Also aryl halides are less reactive, they do not conduct the Friedel-Crafts reaction with benzene.

The reaction would be

Hence, correct option (C).$C_6{H}_{5}Cl$
