(a) Account for the following :
(i) Tendency to show oxidation state decreases from oxygen to tellurium.
(ii) Acidic character increases from to .
(iii) Moist gas acts as a reducing agent.
(b) Draw the structure of an oxoacid of sulphur containing linkage.
(c) Complete the following equation :
(a)
(i) Tendency to show oxidation state decreases from oxygen to tellurium because of decrease in electronegativity .
(ii) Acidic character increases from to .
(iii) Moist gas acts as a reducing agent because of decrease in bond dissociation enthalpy from HF to HI.
(b)
(c) 2XeF2 + 2H2O 2Xe + 4HF + O2
