What is the correct order of electronegativity of Cl atoms in HClO, HClO2, HClO3 and HClO4 ?

According to the question the oxidation states of Cl are in given series of oxy acids as follows:

HOCI (Chlorine +1 oxidation state) 

HOCIO (Chlorine +3 oxidation state) 

HOClO₂ (Chlorine +5 oxidation state) 

HOCIO₃ (Chlorine +7 oxidation state) 

The hydrogen is bonded to an oxygen rather than to the chlorine in the given oxy acids. Now It is clear that on addition of additional oxygen atoms with chlorine, it's oxidation state also Increases hence acidity as well as electronegativity both increase linearly.

We know that "Electronegativity is the property of pulling the bonding electron pair towards itself". Higher the oxidation state means more electrons attracted towards thus the atom has more oxidation state (+) is more electronegative.  So electronegativity of Cl follows:

                    "HCIO < HCIO₂ < HClO₃ < HClO₄."

Why Chlorine (Cl2) bleaches a substance permanently but sulphuredioxide (SO2) does it temporarily?

Chlorine (Cl₂) bleaches a substance permanently because it is due to oxidation but sulphure dioxide (SO₂) does it temporarily because it is due to reduction.

Why Noble gases are mostly chemically inert?

The inertness to chemical reactivity of noble gases is attributed to the following reasons:

(1)The noble gases except helium (1s²) have completely filled ns²np⁶ electronic configuration in their valence shell.

(2) They have high ionisation enthalpy and more positive electron gain enthalpy.
