Why S02 is oxidising while Te02 is reducing agent |
|
Answer» SO2 is reducing agent because sulphur has d orbital so it can EASILY expand its +4 oxidation state to +6 oxidation state and can behave as reducing agent.. TeO2TeO2, Te is heaver elements ,electrons are reluctant to take part in bond FORMATION due to POOR shielding of d- and f- orbital thus lower oxidation state (+2,-2) becomes more STABLE (inert pair effect) and hence TeO2TeO2 is oxidising agent |
