Acid-base strength oxyacids

Many detailed discussions have been published on the effects of substituents on the strengths of organic acids and bases/ We have seen that caution is necessary in interpreting small differences in dissociation constants in terms of molecular models, and this chapter will deal only with a few of the more striking effects, with special reference to some which are of interest in reaction kinetics. We shall consider first the strengths of hydrides and oxyacids of different elements. 

Based on molecular structure, arrange tbe oxyacids in order of increasing acid strength. Explain your choice.
