The correct statements about $IC{l}_4^{-}$ and $I{O}_4^{-}$ is/ are

Periodates are stronger oxidizing agents $IC{l}_4^{-}$ have square planar structure with two lone pairs occupying the opposite corners of octahedron $IC{l}_4^{-}$ ion is formed by the addition of $C{l}^{-}$ ion to $IC{l}_3.$ So it is polyhalide. $I{O}_4^{-}$ is oxoanion of oxoacid $HF{O}_4.$ I-Cl bonds in $IC{l}_4^{-}$ are only single bonds but the I-O bonds in $I{O}_4^{-}$ are 3 double and one single bonds
