Account for the following: (a) Reducing character decreases from SO2

1.	Account for the following: (a) Reducing character decreases from SO2 to TeO2. (b) HCIO3 is a stronger acid than HCIO. (c) Xenon forms compounds with fluorine and oxygen only.
Answer» (a) Stabilty of higher oxidation state decrease down the group from S to Te/stability of lower oxidation state increases down the group from S to Te. (b) ClO₃ is more stable than ClO^-/ClO₃^- is weak conjugate base than ClO^-/Due to higher oxidation state of chlorine in HClO₃ (c) Fluorine and oxygen are most electronegative and very reactive.

(a) Stabilty of higher oxidation state decrease down the group from S to Te/stability of lower oxidation state increases down the group from S to Te.

(b) ClO₃ is more stable than ClO^-/ClO₃^- is weak conjugate base than ClO^-/Due to higher oxidation state of chlorine in HClO₃
