1.	Arrange the halogens F_2, Cl_2 , Br_2 , I_2 in order of their increasing reactivity withalkanes.
Answer» `I_2 lt Br_2 lt Cl_2 lt F_2` `Br_2 lt Cl_2 lt F_2 lt I_2` `F_2 lt Cl_2 lt Br_2 lt I_2` `Br_2 lt I_2lt Cl_2 lt F_2` SOLUTION :Reactivity decreases down the GROUP as the ELECTRONEGATIVITY or the electrode POTENTIAL of the halogen decreases down the group. Thus, option (a ) is correct
