We know that halides are *ortho*, *para* directing for EAS reactions and we consider the electronic stabilization effect as the reason for it. According to me, the order should be 1 > 2 > 3 > 4 because fluorine will give better electronic stabilization due to P(pi) – P(pi) bonding, and steric effect of iodine will reduce the amount of *ortho* product


But the answer given is 4 > 3 > 2 > 1.
