The incorrect statement is:
\( \mathrm{F_2} \) is more reactive than \( \mathrm{ClF} \)
On hydrolysis \( \mathrm{ClF} \) forms \( \mathrm{HOCl} \) and \( \mathrm{HF} \)
\( \mathrm{F_2} \) is a stronger oxidizing agent than \( \mathrm{Cl_2} \) in aqueous solution
\( \mathrm{Cl_2} \) is more reactive than \( \mathrm{ClF} \)
