This is a short answer type question as classified in NCERT Exemplar
The electron donating group increases the reactivity in electrophilic substitution reaction whereas the electron withdrawing group decreases the reactivity in electrophilic substitution.
Thus, the order of reactivity

The benzene here would undergo Friedel-Crafts alkylation reaction where carbocation is formed as an intermediate, thus secondary carbocation is formed as an intermediate due to its greater stability than that of the primary carbocation.
The final product obtained is

The rate-determining step involved in the reaction is
CH3-CH=CH2 + HX → CH3-CH+-CH3 + X-
So the rate-determining step depends on the bond energy of HX i.e. higher the bond energy lesser would be reactivity.
Thus the order of reactivity of these halogen acids is
HI>HBr>HCl

The bond energy of HCl is higher than that of HBr thus it is not cleaved by free radical mechanism to exhibit peroxide effect. However in case of HI the bond energy is so low that the iodine radical forms readily and after formation it combines to form an iodine molecule.
