Interhalogen compounds are more reactive than halogens ( except fluorine ). This is because \mathrm{X-X'} bond in interhalogens is weaker than \mathrm{X-X} bond in halogens except \mathrm{F-F} bond .

So, \mathrm{ICl} is more reactive than \mathrm{I_{2}} and because of \mathrm{I-Cl} bond is weaker than \mathrm{I-I} bond.

Hence the correct option is 4.
