Give reasons :
(i) SO2 is reducing while TeO2 is an oxidizing agent.
(ii) Nitrogen does not form pentahalide.
(iii) ICl is more reactive than I2 (3)
(i) Because stability of higher oxidation state decreases as we move down the group / S is more stable in higher (+6) oxidation state whereas Te is more stable in +4 oxidation state. (1)
(ii) Due to absence of d orbital . (1)
(iii) Because I – Cl bond is weaker than I-I bond. (1)
