SO2 / SO3 / (SO3)2- / (SO4)2- and SCl2 chemical compounds arrange the electronegativity ascending order of S atom give the reasons?

Oxidation state and electronegativity....

The oxidation state of an element in a compound is an assigned number. It is also said to be the charge on an atom if all of the bonds were 100% ionic. Of course, we know that that isn't the case, since there are no 100% ionic bonds. Electronegativity is a measure of an atom's ability to attract shared pairs of electrons. One doesn't measure electronegativity experimentally, but some versions of electronegativity are calculated from average bond energies and others from the average of the bond energy and the electron affinity. I've also run across bits and dabs which refer to slight variations of electronegativity with oxidation state, suggesting that as the oxidation number of an element increases so does the electronegativity.

For instance SnCl2 is a solid at room temperature, with a melting point around 250C, and which exists as strings of polymers. SnCl4, on the other hand is more like a compound with greater covalent character. SnCl4 is a fuming liquid at room temperature and melts at -34C. Since the bonds in SnCl4 have more covalent character, we might infer that the electronegativity of tin in the +4 oxidation state is higher than tin in the +2 oxidation state. (The closer the two electronegativity values, the greater the covalent character.) But I have no numbers for the electronegativity values to back that up, nor have I seen any in the literature. (But that's not to say that they don't exist, only that I haven't done a very thorough search.) Even Wikipedia alludes to an increase in electronegativity with increasing oxidation state. https://en.wikipedia.org/wiki/Electronegativity#Va...

Here the species are arranged by increasing oxidation state. The oxidation state is assigned based on assuming that Cl is -1 and O is -2, and that the sum of the oxidation state is zero for a compound, or the charge on the ion.

+2.........+4........ +4............ +6 ........ +6 ................ Assigned oxidation state

SCl2 .... SO2 .... SO3^2- .... SO3 .... SO4^2-

------ increasing electronegativity? ----->

If there is a connection between the oxidation state and the electronegativity, then we might assume a slight increase in electronegativity as the oxidation state increases.

is that really the question you mean to ask? arrange the electronegativity of the "S" in ascending order?

S has electronegativity = 2.58

are you sure the question isn't... "arrange the OXIDATION STATE of S in ascending order?"
