Oxidising power of halogen molecules decreases in the order : F2, Cl2, Br2, I2. ... the later two factors more than compensate the less negative electron gain enthalpy of F2 . as a result , electron reduction potential of F2 is higher than that of Cl2 thus F2 is much stronger oxidising agent than Cl2.
