Dear sunindra Kanghujan

The oxiding power of HClO4, HClO3, HCLO2, HClO are in the order 

 HClO >HCLO2 >HClO3>HClO4 because the oxidising states of chlorine in HClO4, HClO3, HCLO2, HClO are 7,5,3,1 respectively so HClO with lowest oxidation state of chlorine have greatest tendency to get oxidised and increase its oxidation state.

Hope this has helped you Smile

becoz, 
 higher the oxidation no. higher is the oxidizing power. 

for e.g.

in hclo o.n is -1

in hclo2 o.n is -3.

							because of HClO4 is more stable than other oxyacids of chlorine so its oxidizing power is low.

							The oxiding power of HClO4, HClO3, HCLO2, HClO are in the following order:
                HClO >HCLO2 >HClO3>HClO4
 because the oxidizing power of oxyacids of chlorine is inversely related to the thermal stability of these acids i.e. higher the thermal stability, lower will be oxidizing power of the oxyacid and vice versa. For example the HClO4 is most stable so it has lowest oxidizing power amongst the oxyacids of chlorine. The order of thermal stability of oxyacids of chlorine is HClO4>HClO3>HClO2>HClO.

							Actually with increase in oxidation state of the central atom, the X-O bond acquires more amount of covalent character due to polarisation, hence the electron deficiency gets somehow compensated. Thus the oxidizing power decreases. Moreover the X-O bond acquires partial double bond character in the compounds of higher oxidation state. Hence in order to get reduced, X-O bond has to be broken which requires more energy.

Bcoz here oxidising power is asked which refers​to loose of electrons so the one having lowest oxidation state will have highest oxidising power as it has electrons so it can easily loose them

							The partial double bond character in HClO4 is the highest as there are 3 Cl=O bonds  and also the highest when compared to the rest so it is thermally the most stable. Now coming to the oxidizing power, it basically means the ability to Gain Electrons, remember that pal,  to gain electrons and Oxidize Others. Oxidizing power concerns itself to oxidize others. So HClO4 being the most stable does not gain electrons and the Enthalpy of its gaining electron is very low (assuming the magnitude of enthalpy not its sign).  And hence the reaction of HClO gaining electrons is more feasible and hence the best oxidizing agent.

							Just see their structures hclo4 is resonance stablised so has least probability of accepting an electron , so among them hclo will accept electron more easily due to no resonance

The oxidising power of oxy acids depends on its oxidation state.I.e. higher the oxidation state of chlorine stronger will be the oxidising power.Hence oxidising strength of oxyacids are in the following order:
HClO>HClO2>HClO3>HClO4 and so on.

All of the above answers are wrong. Higher the oxidation state, higher the tendency to get reduced meaning higher the oxidising power. This should imply that HClO4(Cl at +7 oxidation number) should oxidise more than HOCl(Cl at +1 oxidation number) right? The actual explanation for why HClO4 is less oxidising than HOCl is that HOCl performs what is referred as bleaching. In this process, actual Oxygen is released which is a better oxidising agent than most other compounds irrespective of oxidation state similar to how KMnO4(with Mn at +7) is a worse oxidising agent than K2Cr2O7(Cr at +6) , due to Standard Oxidation and Reduction Potential values.
Please do not approve scientifically wrong answers that appear logically correct.

in acidic conditions Mn(+7)changes to Mn(+2) which is more stable than Cr(+3).So permanganate is a better oxidising agent than dichromate.But this cannot be applied here is the problem.
