Vedclass · Answer

(A) Atom $X$ belongs to group $17$ and is not in the second period,so $X$ could be $Cl$,$Br$,or $I$. The general formula for the most acidic oxyacid of halogens is $HXO_4$ (e.g.,$HClO_4$,$HBrO_4$,$HIO_4$). Statement $A$ claims the most acidic oxyacid is $HXO_3$,which is incorrect. The highest oxidation state for group $17$ elements is $+7$. Halogens can form interhalogen compounds with other elements of their group. Oxides of halogens are acidic in nature,so their aqueous solutions have a $pH < 7$.

Atom $X$ belongs to group $17$ $(VIIA)$ and is not present in the second period. Choose the incorrect statement regarding $X$ $:-$
