Identify the incorrect statement from the following :

The acidic strength of $$\mathrm{HX}(\mathrm{X}=\mathrm{F}, \mathrm{Cl}, \mathrm{Br}$$ and $$\mathrm{I})$$ follows the order: $$\mathrm{HF}>\mathrm{HCl}>\mathrm{HBr}>\mathrm{HI}$$.

Fluorine exhibits $$-$$1 oxidation state whereas other halogens exhibit $$+1,+3,+5$$ and $$+7$$ oxidation states also.

The enthalpy of dissociation of $$\mathrm{F}_2$$ is smaller than that of $$\mathrm{Cl}_2$$.

Fluorine is stronger oxidising agent than chlorine.
