Account for the following.
(a) ICl is more reactive than I2
(b) When Cl2 reacts with excess of F2, ClF3 is formed and not FCl3.
(a) It is because bond dissociation energy of ICl is less due to polarity in the molecule as compare to I2 which is non polar.
(b) It is because fluorine is more electronegative than chlorine so F can-not aquire +3 oxd. State.
