The correct statement(s) about the oxoacids, $$HCl{O_4}$$ and $$HClO$$ is (are)

The central atom in both $$HCl{O_4}$$ and $$HClO$$ is $$s{p^3}$$ hybridized

$$HCl{O_4}$$ is more acidic than $$HClO$$ because of the resonance stabilization of its anion

$$HCl{O_4}$$ is formed in the reaction between $$C{l_2}$$ and $${H_2}O$$
