Which incorrect statement ?

AAll halogens form oxyacids.
BAll halogens show -1, +1, +3, +5, +7 oxidation states.
Correct Answer
CHydrofluoric acid forms $$KHF_2$$ and $$ K_2F_2$$ and attacks glass.
DOxidising power is in order $$ F_2>Cl_2>Br_2>I_2$$.

Solution

Fluoride doesnt show $$-1$$ oxidation state,
Oxidising power is in order $$ F_2>Cl_2>Br_2>I_2$$ due to their reducing nature (because of high electronegativity).
